Top Free DSA Courses 2020

Data Structures & Algorithms (DSA) is of the core topic of computer science & engineering. Most of the product-based companies, such as Amazon, Google, Mircosoft, heavily rely on your DSA knowledge.

In this article, we will discuss Top Free DSA Courses, through which you can learn DSA & secure your position in Product Based Companies.

Note: Read the complete article, so that you find the right course for yourself. You may require a student account with Coursera to access some of these free courses!

Why learn Data Structures?

In today’s world, companies need solutions as well as insights about the efficiency of all the algorithms that we use in order to solve our problems. Better & efficient algorithms help us in the evaluation of the problem, which in turn will help us find the lightest weight solution.

Indirectly DSA helps you proving accurate outputs for your problems by stating you the efficiency of algorithms making it easy to choose between options.

Data structure is nothing but the organization, management as well as storage of data in an efficient manner wherein its manipulation and modification is easy. We use DSA to make optimal solutions to the problems.

Here are the top 4 data structure and algorithm courses:

1.Algorithms Part I by Princeton University

This course focuses on the crucial concepts of the data structures which are very important as per the respect of a programmer. I

The course emphasis highly on applications and scientific performance analysis of Java implementations. Its initial lessons aim to talk about the basics of searching algorithms and graph and string-processing algorithms.

It gives a deep understanding of the approach to take in order to analyze algorithms taking dynamic connectivity problem in mind with the help of quizzes which are present in all the modules.

The course is designed such that it will help you gain the overall and total understanding of computational experiments and apply these techniques to relevant projects.

By the end of the course, you will be able to apply the techniques in relevant projects, & master DSA.
