The computer science industry goes hand in hand with algorithms and data structures. They act as the foundation for all other areas of computer science and development. This is the reason why big companies such as Facebook, Google and Microsoft look to hire programmers who are knowledgeable with data structures and algorithms.

Being educated in data structures and algorithms (DSA) can be very advantageous to your career, whether you are looking for a new job or trying to enhance your skills. Thankfully for you, you do not have to spend loads of fees in a university or college to get a data structures and algorithms course or a python programming course. Now that most things are done online, you can get the best data structures and algorithms courses. And you will not have to pay a massive sum of fees either.

In this article, we have made a list of some of the best data structures and algorithms courses that you can get online, and they can assist you in learning one of the most in- demand skills in today’s time and age.

1. Algorithms & Data structures Part 1 and 2 — by Coursera

You will learn about the fundamental data structures and algorithms covered in this course that are used in practical applications. As you might have already guessed, this course is divided into two parts.

In the first part, you will study the trade-offs involved in selecting each data structure, as well as retrieval, traversal, and update algorithms. And the second part of the course will teach you about linked stacks, lists, queues, hash tables and binary trees.

2. Data Structures and Algorithm Course — by Scaler Academy

Scaler Academy by InterviewBit offers a carefully crafted course that will help you master even the most complex data structures and algorithms (DSA) topics quickly and easily. There are courses for all levels of skill, including beginners, intermediates, and experts.

3. JavaScript Algorithms and Data Structures Masterclass — by Udemy

In addition to basic topics such as a binary tree, array, and linked list, the course also focuses on advanced topics like graphs, heaps, and Dijkstra’s Shortest Path Algorithm.

You will learn more than just data structures; you’ll also learn how to use Big O notation to analyse the time and space complexity of your code and how to use space-time trade-offs to reduce it.

4. Data structure course — by NPTEL

This NPTEL data structure and algorithm course will teach you how to design and implement various basic and advanced data structures. This course will:
(a) introduce different techniques for representing the data in the real world,
(b) develop applications using data structures, explain the concept of data security and management, and
(c) increase the efficiency of any algorithm by using the appropriate data structure.


There are many more online platforms and institutes where you can get a data structures and algorithms course. This article provided four of the best courses you can pursue to enhance your skill set.
