• It typically includes simple coding challenges that test your grasp of core programming concepts like loops, conditionals, arrays, and string manipulation.
• Alongside coding, you'll face aptitude-based questions that cover logical reasoning and basic mathematics. 

Here are some common Zoho interview questions you might face, along with explanations and sample codes:

1. How would you write a program to check if a number is prime?

How to Answer:

• Explain the logic: A prime number is only divisible by 1 and itself. To check for primality, iterate from 2 to the square root of the number.
• Optimize the process: Iterating up to the square root reduces unnecessary checks, improving efficiency for larger numbers.
• Discuss performance: Mention that this method reduces time complexity to O(√n), making it more efficient than checking divisibility up to n.

Sample Answer:

To check if a number is prime, iterate from 2 to the square root of the number. If the number is divisible by any value in this range, it's not a prime.

Here’s an efficient way to check whether a number is prime using Python:

def is_prime(n):
    if n <= 1:
        return False
    for i in range(2, int(n**0.5) + 1):
        if n % i == 0:
            return False
    return True

2. How can you reverse a given string using Python?

How to Answer:

• Explain Python's powerful slicing feature to reverse a string.
• Mention that the syntax [::-1] allows for efficient and concise string reversal.
• Emphasize that this method is simple, clean, and highly optimized for performance.

Sample Answer:

Python's slicing feature can be used to reverse a string.

Here’s how:

def reverse_string(s):
    return s[::-1]

Example: print(reverse_string("hello"))  
Output: "olleh"

Aim for a strong foundation in such core programming concepts. A Professional Certificate Program in Data Science and Business Analytics can be a smart next step to boost your technical and analytical expertise.

3. How do you find the largest number in an array?

How to Answer:

• Start by explaining the need to iterate through the array to compare each number.
• Mention that keeping track of the largest value encountered will allow you to find the maximum.

Sample Answer:

Iterate through the array and keep track of the largest number found.

Here’s how this can be done using Python:

def find_largest(arr):
    largest = arr[0]
    for num in arr:
        if num > largest:
            largest = num
    return largest

Example: print(find_largest([10, 45, 2, 67, 34]))  
Output: 67

4. How would you check if a string is a palindrome?

How to Answer:

• Explain that a palindrome is a string that reads the same forward and backward.
• You can check if the string is equal to its reverse using Python's slicing feature.

Sample Answer:

To check if a string is a palindrome, you need to compare the string with its reverse. A palindrome is a word or phrase that reads the same forward and backward, such as "madam" or "racecar." In Python, you can easily reverse a string using slicing and check if it matches the original string.

Here's how you can do it:

def is_palindrome(s):
return s == s[::-1]
# Example
print(is_palindrome("madam"))  # Output: True
print(is_palindrome("hello"))  # Output: False

This method works by using the slice notation [::-1] to reverse the string, then compares it with the original string. If both are the same, the function returns True, indicating the string is a palindrome.

5. How would you solve a logic puzzle that involves identifying the next number in a sequence?

How to Answer:

• Start by explaining the importance of identifying the pattern within the sequence. Common patterns include arithmetic progression (constant differences), geometric progression (multiplying by a constant), squares, or other mathematical relationships.
• Walk through the thought process of recognizing these patterns in the sequence.
• Provide an example to showcase how you can identify the pattern and predict the next number.
• Mention that logical puzzles like this assess your ability to spot trends, think critically, and apply basic mathematical principles.

Sample Answer:

To solve a logic puzzle involving identifying the next number in a sequence, start by analyzing the relationship between consecutive numbers. Look for consistent patterns like differences, ratios, or any other mathematical progression.

For example, consider the sequence: 2, 4, 8, 16, ?

• The pattern here is that each number is multiplied by 2 to get the next number.
• So, the next number in the sequence will be 16 * 2 = 32.

Thus, the next number in the sequence is 32.

In cases where the pattern isn't immediately clear, consider other types of progressions, such as adding a constant value, multiplying, or applying squares and cubes. Recognizing such patterns is key to solving logic puzzles effectively.

6. How can you swap two numbers without using a temporary variable?

How to Answer:

• Start by explaining that in many programming languages, swapping two variables typically requires a temporary variable. However, Python offers a more elegant solution using tuple unpacking.
• Explain that Python allows multiple variables to be assigned simultaneously, which makes swapping values without an extra variable straightforward.
• Provide a concise code example to demonstrate this technique.
• Highlight that this method is efficient, easy to understand, and widely used in Pythonic code.

Sample Answer:

In Python, values can be swapped directly using tuple unpacking.

Here’s an example of how this is done:

def swap_numbers(a, b):
    a, b = b, a
    return a, b
# Example
num1, num2 = swap_numbers(5, 10)
print(num1, num2)  # Output: 10 5

7. Can you solve a basic math problem that involves calculating percentages?

How to Answer:

• Start by explaining the basic formula for calculating percentages: (part / whole) * 100.
• Clarify that you need two values: the part (the portion of the total) and the whole (the total value).
• Walk through an example calculation to show how the formula is applied.
• Emphasize that this is a fundamental skill often used in everyday calculations, finance, and data analysis.

Sample Answer:

Divide the part by the whole and multiply by 100 to get the percentage.

To calculate a percentage, you need to divide the part (the portion of the total) by the whole (the total value), and then multiply by 100.

For example, if you want to calculate what percentage 25 is of 200:

• Formula: (25 / 200) * 100
• Calculation: 0.125 * 100 = 12.5%

So, 25 is 12.5% of 200. This simple calculation is useful in many contexts, from determining discounts to analyzing data.

• You can expect more challenging coding problems focused on data structures and algorithms to assess how well you apply logic and structure to solve problems. 
• Additionally, depending on the specific role you're applying for, there may be domain-based questions.

Here are some common intermediate Zoho interview questions:

1. How do you write a function to find the missing number in an array of numbers from 1 to n?

How to Answer:

• Explain the approach of finding the missing number by calculating the expected sum of numbers from 1 to n using the formula n * (n + 1) / 2.
• Then, subtract the actual sum of the array from the expected sum to find the missing number.
• Provide the code example for clarity.

Sample Answer:

To solve this, calculate the expected total using the formula for the sum of the first n numbers and subtract the actual sum of the array.

Here’s how the missing number can be found:

def find_missing(arr, n):
    expected = n * (n + 1) // 2
    return expected - sum(arr)

2. How do you implement a linked list and write a function to reverse it?

How to Answer:

• Start by explaining how a linked list is a collection of nodes where each node contains data and a reference (or pointer) to the next node.
• Describe the process of reversing the list by iterating through it and changing the next pointers.
• Provide the code example for implementing a singly linked list and reversing it.

Sample Answer:

Traverse the list and reverse the next pointers iteratively.

The below code represents how to implement a singly linked list in Python and reverse it using an iterative approach.

class Node:
    def __init__(self, data):
        self.data = data
        self.next = None
class LinkedList:
    def __init__(self):
        self.head = None
    def push(self, data):
        new_node = Node(data)
        new_node.next = self.head
        self.head = new_node
    def reverse(self):
        prev = None
        current = self.head
        while current:
            next_node = current.next
            current.next = prev
            prev = current
            current = next_node
        self.head = prev
    def print_list(self):
        temp = self.head
        while temp:
            print(temp.data, end=" ")
            temp = temp.next

3. How do you perform a binary search on a sorted array?

How to Answer:

• Explain that binary search is a divide-and-conquer algorithm used on sorted arrays. It checks the middle element and decides which half to search next, reducing the search space in each iteration.
• Describe the key steps: calculate the middle index, compare the target with the middle element, and adjust the search range accordingly.
• Provide the code example for binary search.

Sample Answer:

Binary search is a fast way to find an item in a sorted array. It works by checking the middle element and deciding whether to look in the left or right half. This process continues until the item is found or the search range becomes empty.

Here’s how its executed:

def binary_search(arr, target):
    left, right = 0, len(arr) - 1
    while left <= right:
        mid = (left + right) // 2
        if arr[mid] == target:
            return mid
        elif arr[mid] < target:
            left = mid + 1
        else:
            right = mid - 1
    return -1

4. How can you solve the problem of finding the longest substring without repeating characters?

How to Answer:

• Start by explaining the sliding window technique. This method involves maintaining a window of unique characters and adjusting its size dynamically as you move through the string.
• The left pointer of the window is adjusted whenever a duplicate character is found.
• Provide the code example.

Sample Answer:

Solve the problem using a sliding window technique that maintains a set of unique characters and adjusts the window to track the longest valid substring.

Here’s how the sliding window technique can be used in Python:

def longest_substring(s):
    seen = set()
    left = 0
    max_len = 0
    for right in range(len(s)):
        while s[right] in seen:
            seen.remove(s[left])
            left += 1
        seen.add(s[right])
        max_len = max(max_len, right - left + 1)
    return max_len

5. What is the difference between a linked list and an array?

How to Answer:

• Compare linked lists and arrays based on key characteristics such as memory allocation, access time, and insertion/deletion efficiency.
• Linked lists are dynamically sized, and insertion/deletion is more efficient at the ends or in the middle.
• Arrays are fixed in size, with constant-time access, but insertion and deletion can be costly due to the need to shift elements.
• Use the following points for comparison:
  • Memory: Linked List (Dynamic), Array (Fixed Size)
  • Access Time: Linked List (O(n)), Array (O(1) for direct access)
  • Insert/Delete: Linked List (Efficient at ends/mid), Array (Costly)

Sample Answer:

Here is an overview: 

Use Case: Use linked lists for frequent insertions/deletions; arrays for random access needs.

6. What is the difference between merge sort and quick sort?

How to Answer:

• Explain that both merge sort and quick sort are divide-and-conquer algorithms used for sorting, but they differ in their approach and performance characteristics.
• Merge sort has a stable sorting process with O(n log n) time complexity, but it requires extra space for the merged arrays.
• Quick sort, while also having an average time complexity of O(n log n), can degrade to O(n²) in the worst case. It is in-place, meaning it doesn’t require extra space.
• Use the following comparison points:
  • Time Complexity: Merge Sort (O(n log n)), Quick Sort (O(n log n) average, O(n²) worst)
  • Stability: Merge Sort (Stable), Quick Sort (Not always stable)
  • Space: Merge Sort (Extra space), Quick Sort (In-place)

Sample Answer:

Here is an overview:

Use Case: Use merge sort for large datasets needing stability. Quick sort is fast but riskier.

7. What is the time complexity of binary search in data structures?

How to Answer:

• Start by explaining that binary search is used to find an element in a sorted array by repeatedly dividing the search space in half.
• Highlight that the algorithm checks the middle element and then eliminates half of the search range, reducing the number of comparisons.
• Mention that the time complexity of binary search is O(log n), where n is the number of elements in the array.
• Provide the example where binary search is faster than linear search, which takes O(n) time in the worst case.

Sample Answer:

Binary search is an efficient technique used to search elements in a sorted array. It works by continuously dividing the search range in half and checking whether the target lies on the left or right side of the middle element. 

• This method significantly reduces the number of comparisons, making it faster than linear search. 
• While linear search takes O(n) time in the worst case, binary search completes the task in O(log n) time, where n is the total number of elements. 

8. How do dynamic programming and recursion differ from each other?

How to Answer:

• Explain that both dynamic programming and recursion break problems into smaller subproblems, but they approach the problems differently.
• Discuss that recursion calls the same function repeatedly with smaller inputs, which can result in inefficiency due to redundant calculations.
• Explain that dynamic programming improves upon recursion by storing already computed results (memoization), preventing redundant calculations and improving efficiency.
• Provide an example such as calculating Fibonacci numbers to show the difference in performance.

Sample Answer:

Dynamic programming and recursion are both techniques for solving complex problems by breaking them down into smaller subproblems, but they differ significantly in how they handle these subproblems.

Recursion calls the same function repeatedly with smaller inputs, often leading to repeated calculations of the same values. This can result in inefficient performance, especially for problems with overlapping subproblems, like calculating Fibonacci numbers.

On the other hand, dynamic programming improves upon this by storing the results of already solved subproblems, so they don’t need to be recalculated. This technique is called memoization. By remembering past results, dynamic programming avoids redundancy and significantly boosts efficiency. 

9. What is the major difference between a shallow copy and a deep copy?

How to Answer:

• Explain that both shallow and deep copies are methods for copying objects, but they differ in how nested elements within the object are handled.
• Describe that a shallow copy copies the object but keeps references to nested objects, meaning changes in the nested objects will affect both the original and the copy.
• Contrast this with a deep copy, where a completely new object is created, along with new copies of the nested elements, ensuring the original and copy are independent.
• Mention that deep copying avoids shared references and unintended changes.

Sample Answer:

A shallow copy creates a new object, but instead of duplicating all the nested objects inside it, it simply copies their references. 

• This means the original and the copied object share the same inner elements. 
• As a result, changes made to those nested elements in one will reflect in the other. 

A deep copy goes a step further by creating entirely new instances of the nested objects as well, ensuring that the original and the copy are independent. This avoids accidental changes caused by shared references.

Here are the key differences:

10. What is the difference between stack and queue data structures?

How to Answer:

• Begin by explaining that both stack and queue are linear data structures, meaning their elements are arranged in a sequence.
• Discuss that a stack follows the Last-In-First-Out (LIFO) principle, where the most recently added element is the first to be removed.
• On the other hand, a queue follows the First-In-First-Out (FIFO) principle, where the earliest added element is the first to be removed.
• Provide examples of real-life situations where stacks (like undo operations) and queues (like print queues) are used.

Sample Answer:

Both stack and queue are linear data structures, but they differ in how elements are inserted and removed. 

• A stack follows the Last-In-First-Out (LIFO) approach, meaning the last item added is the first to be removed. 
• In contrast, a queue follows the First-In-First-Out (FIFO) principle, where the first item added is the first to be taken out.

11. How is a stack implemented?

How to Answer:

• Explain that a stack can be implemented using either arrays or linked lists.
• For array-based implementation, elements are added and removed from the end of the array, with an index tracking the top of the stack.
• For linked list-based implementation, elements are added and removed from the head of the list, maintaining the LIFO order.
• Discuss that both methods provide efficient push and pop operations, with linked lists offering more dynamic resizing.

Sample Answer:

Stack can be implemented using either arrays or linked lists. With arrays, elements are added and removed from the end, and the top of the stack is tracked using an index. For linked list implementations, elements are added and removed from the head of the list, maintaining the LIFO order. Both methods provide efficient push and pop operations.

13. What kinds of joins are there in SQL?

How to Answer:

• Explain that SQL joins are used to combine rows from two or more tables based on a related column.
• Describe the four main types of joins: INNER JOIN, LEFT JOIN, RIGHT JOIN, and FULL OUTER JOIN.
• Provide examples or use a simple table structure to highlight the differences between the joins.

Sample Answer:

SQL supports four primary types of joins used to combine data from multiple tables:

• INNER JOIN: Returns records with matching values in both tables.
• LEFT JOIN: Returns all records from the left table and matched records from the right table.
• RIGHT JOIN: Returns all records from the right table and matched records from the left table.
• FULL OUTER JOIN: Returns all records when there is a match in either the left or right table.

Here’s how the four types compare:

14. What is the difference between JRE, JDK, and JVM?

How to Answer:

• Describe each component (JRE, JDK, JVM) and their roles in the Java environment.
• Explain that the JRE provides the runtime environment to run Java applications, the JVM is responsible for executing bytecode, and the JDK is the complete package for developing Java programs.
• Clarify how they work together and their distinct functions.

Sample Answer:

• JRE (Java Runtime Environment) provides the libraries and environment to run Java applications. 
• JVM (Java Virtual Machine) is part of the JRE that executes Java bytecode. 
• JDK (Java Development Kit) is a software development package that includes tools for developing Java programs, along with the JRE.

Here’s how the three compare:

15. When is serialization used?

How to Answer:

• Start by explaining that serialization is the process of converting an object into a byte stream.
• Mention common use cases such as saving objects to files, sending them over networks, or storing them in databases.
• Explain that serialization allows objects to be reconstructed (deserialized) later.

Sample Answer:

Serialization in Java is used to convert an object into a byte stream so that it can be stored in a file, sent over a network, or saved in a database. This allows the object to be reconstructed later, preserving its original state and data.

16. Are NULL values similar to those of zero or empty space in a database?

How to Answer:

• Explain that NULL represents the absence of a value or an unknown data point, not zero or empty space.
• Clarify that zero is a numeric value and a blank space is a character, whereas NULL signifies that no data exists for that field.
• Highlight the difference in handling NULL values in SQL queries and calculations.

Sample Answer:

No, NULL represents the absence of a value or unknown data in a database. It is different from zero, which is a numeric value, and a blank space, which is a character. NULL does not mean empty or zero; it indicates that no data has been provided.

17. What is the difference between a pointer and a reference?

How to Answer:

• Explain that both pointers and references hold the address of another variable, but they behave differently.
• Point out that a pointer can be reassigned to different memory locations, while a reference is an alias for a specific variable and cannot be changed once assigned.
• Discuss when and why you would use each in programming.

Sample Answer:

• A pointer holds the memory address of another variable and allows direct access to it. 
• A reference, on the other hand, is an alias for an existing variable. 
• While pointers can be reassigned and manipulated, references are fixed to the original variable once defined.

18. What is the main difference between call by reference and call by value?

How to Answer:

• Explain the difference between call by reference and call by value in terms of how the function receives arguments.
• In call by value, the function works on a copy of the argument, while in call by reference, the function works on the actual memory address of the argument.
• Provide examples of when each method is used.

Sample Answer:

• In call by value, a function receives a copy of the variable's value, so changes inside the function do not affect the original variable. 
• In call by reference, the function receives the variable's address, allowing it to modify the actual value in memory.

19. What is a virtual function in C++?

How to Answer:

• Explain that a virtual function allows for dynamic polymorphism, enabling derived classes to override functions in the base class.
• Mention that declaring a function as virtual ensures the correct function is called based on the object type at runtime.
• Emphasize the role of virtual functions in supporting dynamic behavior.

Sample Answer:

A virtual function in C++ allows a function to be overridden in derived classes, enabling polymorphism. Declaring a function as virtual in the base class ensures that the correct function is called based on the object type at runtime, supporting dynamic behavior.

20. What is a constructor in C++?

How to Answer:

• Explain that a constructor is a special function in C++ used to initialize objects when they are created.
• Mention that constructors have the same name as the class and do not have a return type.
• Provide an example of a constructor and describe its role in object initialization.

Sample Answer:

A constructor is a special member function in C++ that initializes objects of a class. It has the same name as the class and is automatically called when an object is created. Unlike other functions, constructors do not have a return type.

For example:

class MyClass {
public:
MyClass() { // Constructor
     // Initialize properties here
}
};

1. When should the super keyword be used in Java?

How to Answer:

• Explain that the super keyword refers to the parent class's members (methods or variables).
• It's commonly used when a subclass overrides a method or variable and you still need to access the original implementation from the parent class.
• Additionally, super can be used to explicitly call a parent class constructor when needed.

Sample Answer:

The super keyword in Java refers to members (methods or variables) of a parent class. It’s beneficial when a child class overrides methods or variables from the parent class and you still want to access the original versions. It can also be used to call a parent class constructor from within the subclass explicitly.

2. What are sockets in the context of operating systems?

How to Answer:

• Start by explaining that a socket is a communication endpoint for processes to exchange data.
• Mention that sockets are used in client-server models to facilitate network communication.
• Highlight that sockets are identified by an IP address and port number, which makes them crucial for connecting applications over a network.

Sample Answer:

Sockets are communication endpoints that allow processes, either on the same machine or across different machines, to exchange data. 

• In the client-server architecture, sockets act as the bridge between client requests and server responses. 
• Each socket is identified by an IP address and a port number, making them essential for enabling network communication between applications.

3. What is a software bug?

How to Answer:

• Explain that a software bug is an error or flaw in the code that causes the program to behave unexpectedly.
• Discuss that bugs can range from minor issues to critical errors causing system crashes.
• Mention that bugs usually arise from conditions not anticipated during the development process, such as edge cases.

Sample Answer:

A software bug is an error or flaw in a program's code that causes it to behave unexpectedly or incorrectly. Bugs can range from minor issues like output typos to serious faults that cause system crashes. These errors often stem from edge cases or conditions the developer didn’t anticipate during development.

4. How do stack overflow and heap overflow differ?

How to Answer:

• Explain that both stack and heap are types of memory used by programs, but they serve different purposes.
• Discuss that stack overflow occurs when the stack memory exceeds its limit, often due to deep or infinite recursion.
• Heap overflow happens when the program uses more heap memory than allocated, often due to excessive or uncontrolled dynamic memory allocation.

Sample Answer:

• A stack overflow occurs when a program uses more stack memory, often due to deep or infinite recursion, than is available, causing the application to crash. 
• On the other hand, a heap overflow happens when a program exceeds its allocated heap memory, often due to uncontrolled dynamic memory allocation, leading to performance issues or unexpected behavior.

5. What is a deadlock in operating systems?

How to Answer:

• Explain that a deadlock happens when two or more processes are stuck waiting for resources held by each other.
• Emphasize that deadlock causes the processes to stop executing and the system cannot proceed unless action is taken to resolve it.

Sample Answer:

A deadlock is a situation in which two or more processes are stuck waiting for each other to release resources, preventing each process from proceeding. Since each process is waiting indefinitely, the system reaches a standstill unless external action is taken.

6. How does a switch statement differ from an if-else statement?

How to Answer:

• Explain that an if-else statement evaluates conditions one by one and is versatile for any logical expression.
• In contrast, a switch statement is used when a variable needs to be compared to multiple constant values, offering more readability and efficiency.
• Provide a comparison between the two for clarity.

Sample Answer:

• An if-else statement evaluates conditions one at a time and can handle various logical expressions. 
• A switch statement, however, is used when a variable needs to be compared against multiple constant values, offering a cleaner and more readable structure for such scenarios.

Here’s how the two differ:

7. How can web applications ensure data security?

How to Answer:

• Mention key best practices like encrypting sensitive data, validating user input, and using secure coding techniques.
• Explain the importance of regularly updating software and monitoring for suspicious activity.
• Highlight that data security also involves using authentication, authorization, and securing communications (SSL/TLS).

Sample Answer:

Several best practices should be followed to safeguard data in web applications. These include encrypting sensitive data, validating user input to prevent injection attacks, implementing logging and monitoring for suspicious activity, regularly updating software to patch vulnerabilities, and following secure coding practices during development.

8. How do you implement Dijkstra’s algorithm to find the shortest paths in a weighted graph?

How to Answer:

• Describe Dijkstra's algorithm as a way to find the shortest path from a source node to all other nodes in a graph.
• Mention using a priority queue (min-heap) to keep track of the current shortest path.
• Provide a clear code example to demonstrate the solution.

Sample Answer:

Dijkstra’s algorithm helps compute the shortest distance from a source node to all other nodes in a graph with non-negative edge weights. It uses a priority queue (min-heap) to explore the closest node next and updates the minimum distances as it traverses the graph.

Below is the code that demonstrates the solution:

import heapq
def dijkstra(graph, start):
    distances = {node: float('inf') for node in graph}
    distances[start] = 0
    priority_queue = [(0, start)]
    while priority_queue:
        current_distance, current_node = heapq.heappop(priority_queue)
        if current_distance > distances[current_node]:
            continue
        for neighbor, weight in graph[current_node].items():
            distance = current_distance + weight
            if distance < distances[neighbor]:
                distances[neighbor] = distance
                heapq.heappush(priority_queue, (distance, neighbor))
    return distances
# Example usage
graph = {
    'A': {'B': 1, 'C': 4},
    'B': {'A': 1, 'C': 2, 'D': 5},
    'C': {'A': 4, 'B': 2, 'D': 1},
    'D': {'B': 5, 'C': 1}
}
print(dijkstra(graph, 'A'))  # Output: {'A': 0, 'B': 1, 'C': 3, 'D': 4}

9. How would you design a scalable system for a chat application?

How to Answer:

• Suggest a microservices-based architecture that separates core functionalities (user authentication, messaging, etc.) into independent services.
• Mention using real-time messaging with WebSockets, and discuss message queues for managing message delivery.
• Highlight the use of a NoSQL database for storing messages and user data.

Sample Answer:

To build a scalable chat application, a microservices architecture that separates core functionalities into independent services can be used. Essential components include user authentication for secure access, a real-time messaging service (using WebSockets), a message queue to manage message delivery efficiently, and a NoSQL database.

10. How can you check if two strings are anagrams of each other?

How to Answer:

• Explain that two strings are anagrams if they contain the same characters with the same frequency.
• Suggest sorting both strings and comparing them, which is an efficient way to check for anagrams.

Sample Answer:

Two strings are considered anagrams if they contain the same characters with the same frequency. A simple way to check this is by sorting both strings and comparing them.

Here’s a simple code that checks if two strings are anagrams:

def are_anagrams(str1, str2):
    return sorted(str1) == sorted(str2)
# Example usage
print(are_anagrams("listen", "silent"))  # Output: True
print(are_anagrams("hello", "world"))    # Output: False

11. How would you implement a basic RESTful API?

How to Answer:

• Start by explaining the core concept of a RESTful API, which uses HTTP methods (GET, POST, PUT, DELETE) to interact with resources.
• Mention that each endpoint represents a resource, such as /users or /posts.
• Highlight that frameworks like Flask for Python or Express for Node.js are commonly used to implement RESTful APIs.
• Provide a simple example using one of these frameworks to demonstrate how to set up basic endpoints.

Sample Answer:

To create a basic RESTful API, define endpoints for different resources (like /users or /posts) and handle standard HTTP methods such as GET, POST, PUT, and DELETE. You can use frameworks like Flask (Python) or Express (Node.js) to build and manage these endpoints.
