Course Description

Your Search on Learning Data Structures & Algorithms ends here.  Ds & Algos are very easy if you know how exactly they work! And I am here to show its implementation process with  very easy approach using Whiteboard teaching so that you will master on all the essential concepts to clear the Interviews.

The examples I picked in this course will fine tune your thought process and enhance your logical thinking ability. With the approach of  Whiteboard teaching, You will have practical understanding of how Data structures Problems can be analyzed and solved!!
There are tons of Assignments & Interview Questions with solutions  all over the course for practice so that you can progress in the course confidently

In this course, I use Java to teach the concepts but you can apply these concepts in any programming language. Our focus is on data structures and algorithms, not programming languages and tools.

Below are the list of Data Structure topics you will master from this tutorial


1. Recursion

2. Linked List

3. Stacks

4. Queues

5. Time Complexity

6. Search Algorithms

7. Sort Algorithms

8. Binary Trees

9. Arrays & Heaps

10. Hash Map with its internal working process



By end of this course, you will gain enough confidence in solving the Data Structure puzzle questions and also gain the ability to write algorithms for any given problem

Excellent. I was able to understand all the data structures and algorithms in depth. It is very clearly explained. I feel fortunate to go over this tutorial. Waiting for Part 2.

By Swarupa Chavan on 6/20/2024

Course is absolutely good, each concept explanation is clear. But some topics are missing like array, some sorting and searching algorithms, some data structures. If you include that in this course then it would be more beneficial. and I unable to find part 2 of that course on Udemy.

By Binal Shah on 4/2/2024

Rahul sir you are a great teacher, you explain concepts in very clear way which helps a lot. This course design and flow is very clear, and concepts are very clearly explained. Thank you so much for designing such course.

By Navmi Vishwakarma on 2/24/2024

The course is structured very well. Concepts are explained in an easy-to-understand manner. Quick sort is remaining and that is why I have given 4.5 stars. I'd highly recommend it to someone who is trying to learn DSA and has no idea about it whatsoever.

By Anonymized User on 2/26/2023

The Course made is easy and good to understand. The half star less is only for less examples to practice. More examples should be added for practice

By Shailesh Kumar on 9/30/2022

Rahul is a great teacher . One of the best basic DSA course for noobs like me . Reason for -1 star is because it doesn't contain enough practice problems , that you have to find it yourself. Otherwise it's a good course.

By Swetha J on 9/26/2022

Amazing as always. I Recommend Rahul Shetty courses to beginners as well as experienced. who are eager to learn concepts with clarity. Even a beginner can understand easily and practice assignments and will be able to solve any problems with basics taught in this course. my strategy is I complete a video once and with 2x speed listen to it once again and revise my understanding and then solve problem on my own. Its amazing . Thanks Rahul Shetty for making it so simple I always had fear of Data Structures especially linked lists. yet to complete sorting algorithms videos now I am confident I will overcome fear of sorting algos as well by end of this course.

By Krishna Kamakshi Brahma on 9/6/2022

Wow, these sections are really worth it. After studying DS back in 2013 and having nightmares while solving any problems, Rahul makes it look so easy by making us understand: 1. How to approach a solution for a given problem 2. Design Pseudocode, and solve more minor problems 3. then, at last implementations

By Pawanhans Kohli on 9/2/2022

I finally got some grip over Data structure and algorithms thanks to this course. I never really got that interest from other courses as they were generally boring presentations and it used to go over my head. Thank you so much for sharing your knowledge in lucid and simple way.

By Aneesa Choudhary on 9/2/2022

Thanks Rahul for this wonderful course on Datastructures and algorithms. I finally feel that I have got a hang on DS and Algorithms which I have been struggling to fully understand in my earlier attempts learning them. Perfect pace and clear explanations of all the complex search algorithms. Loved it and looking forward to new updates to the course.
