For every professional programmer, data structures and algorithms (DSA) are the two most fundamental areas to master. The more efficient you are in data structures and algorithms, the better you can evaluate the efficiency of an algorithm, make your code scalable, and effectively utilize memory. If you want to learn algorithms and data structure and are looking for online courses to start your journey, then here are some of the best data structures and algorithm courses.

In this article, we have included courses for data structures and algorithms in Java, Python, C, and C++ so that you understand the implementation better in different programming languages. Before we dive into the top data structures and algorithms courses, let’s take a look at why these skills are important.

Importance of mastering Data Structures & Algorithms:

Data Structures and Algorithms are the building blocks to design and develop an efficient software application. Data structures store objects and allow their manipulation, and they can be –

  • Linear – arrays, stacks, linked lists, or queues
  • Nonlinear – trees, graphs, tables, or sets

On the other hand, algorithms help define clear steps and conceptualizing solutions in terms of distinct steps in a process. Data Structures and Algorithms alter the system by providing accessibility of data and increasing the product’s efficiency. They also aid in analyzing the time and space performance of algorithms.

Why should programmers learn data structure and algorithms? Well… The difference between average and great programmers is often due to knowledge of data structure and algorithms. Whether you are beginning your programming journey – or going back to explore the fundamentals, mastering DSA would make a world of difference.

In this article, we have put together a list of the best data structures and algorithms courses to help you master these topics. These online courses will provide you sound understanding and learning of the subject. These courses will also help you crack interviews in the software engineering and data science fields. Here is the curated list of data structure and algorithms courses:
