Data Structure and Algorithm

Introduction

"This guide is a work in progress. If you have any suggestions, please feel free to contact me on LinkedIn If your suggestions are valuable, I will add them to the list and give you credit."

Data structures by themselves aren’t all that useful, but they’re indispensable when used in specific applications, like finding the shortest path between points in a map, or finding a name in a phone book with say, a billion elements (no, binary search just doesn’t cut it sometimes!). By Algosaurus

Choose a programming language

I would suggest C or C++ for learning data structures and algorithms. Building a strong foundation is important so choose a language that is close to the hardware. C and C++(not sure why some people hate c++ ) are the best choices for this. After you get a good grasp of data structures and algorithms, you can start preparing in more high-level languages like Python, Java, etc. As these languages are easier to implement in interviews.

For other langauges more resources can be found here (opens in a new tab) I would suggest getting decent in the lanagauge you choose before starting with data structures and algorithms.

You are free to make your own choices here.

Choose how to learn

  1. Video tutorials
  2. Problem Solving driven approach

Reasons

  1. Abdul Bari covers all the fundamental data structures and algorithms in such a way that you will never forget them. He explains the concepts in a very simple way . I would highly recommend his course.
  2. Striver's SDE sheet is all you need to learn data structures and algorithms. I would go further and say if already have know c or c++ just start here you won't regret it
  3. Neetcode is similar to Striver's SDE sheet but it has less problems than Striver's SDE sheet so you can choose between the two depending on the time you can allot . It is a great resource to learn data structures and algorithms.
