What are Data Structures?

Data structures are methods of gathering and organizing data. Using data structures helps you in applying certain operations on your data effectively. We all know how beneficial it is to keep things organized. Having a designated location for everything helps you find that thing later, enabling you to save time and energy. 

A data structure helps your program similarly. It allows you to store and arrange data properly so you can use it through different operations. There are different types of data structures, and they all have certain advantages (and disadvantages). You should choose a data structure according to the requirements of your problem. The data structure should make your solution more efficient and less complicated when you implement it. 

What are the different types of data structures?

The data we use across platforms is not uniform. Data comes in different forms and aspects, giving way to developing data formats and management skills. We can classify data mainly into two forms — linear data and non-linear data. While linear data comprises arrays, queues, stacks, and linked lists, non-linear graphs, and trees.
With upGrad’s data structure course free, you will learn more about the functions of these varieties of data structures.

Why is data structure important?

At a time when information is growing exponentially, and data is easily accessible, finding efficient ways to manage the data becomes crucial. This is where we learn the importance of data structure.

Data structures free online course teaches you the implementation of data structures that helps to enhance data accuracy and produce efficient codes on a need basis.

Further upGrad’s data structures and algorithms course free of a complex syllabus model, will help you kickstart your career as a software developer and implement smart data structures.

What is an Algorithm?

In layman terms, algorithms are a collection of steps you can use to solve a problem. You can say every algorithm is a solution. Another great simile for algorithms would be recipes.

Like a specific recipe helps you cook a particular dish with certain ingredients, an algorithm helps your machine solve a particular problem with a particular input. 

As algorithms are lists of steps, you can see why they are quite popular. When a chef creates a particular recipe for a dish, they can share it with others, and they would be able to cook the same dish by following that recipe. Similarly, you can use an algorithm to solve specific problems and share it with others who might want to fix that same issue.

An algorithm is not a complete program or code. You can express an algorithm through a flowchart or pseudocode.

Key Difference between Data Structure and Algorithm

A data structure is organising, managing and storing data while the algorithm involves systematic steps to achieve the output.

The steps involved in algorithms can use one or more data structure(s) while delivering the output. In computer science, several algorithms rely heavily on these data structures that give programmers the efficient tools to handle and manage a pile of data.

While it’s difficult to explain these terms to students new to the world of computer science, they can learn the basics through  data structures and algorithms free course.

Why Learn Data Structures and Algorithms (DSA)?

There are many benefits to learning DSA. Here are some of the most prominent reasons why you should consider learning data structure and algorithms:

Interviews 

Do you ever wonder why the packages from tech giants such as Google, Facebook, or Microsoft are so big? Why do they pay their engineers this high? That’s because they want candidates who can think out of the box and develop creative solutions for their enterprise. These engineers have to create unique algorithms to solve the highly complex these companies face. All of these companies have millions and billions of users.

That’s why a solution that benefits them by even 0.01% would make a huge difference. Learning and using algorithms will help you explore their applications as well. You can prepare yourself for these companies’ interviews by solving various problems using algorithms and data structures. You should know how to use different algorithms to fix various types of issues. 

Efficiency

What’s more comfortable, finding a book in a library or a pile of books with the same quantity as the library? 

It’s easier to find a book in a library because they are well-organized and arranged. You’ll have to spend a lot more time and energy to find the same book in a huge pile. Data structures benefit you the same way. They reduce the time and memory your program needs to complete a task. Algorithms help you similarly. Instead of writing multiple lines of code, you can implement an algorithm and get a result much quicker. 

Scalability

Another significant advantage of data structures and algorithms offer they are scalable. This means if you expand the size of a problem, the solution would still remain the same, only the quantity of input and output would change. We can compare algorithms with recipes to explain this feature. 

Whether you have to prepare a cake for two guests or 200, the fundamental steps and proportions of ingredients would remain the same, only the quantity of ingredients would change. DSA works similarly. That’s why companies use them extensively. It’s another reason why tech giants rely heavily on DSA. They deal with vast quantities of users and servers, so scalability is a must-have for their solutions.
