DSA Important Questions from Scratch

Hey there!

This repo contains some important and frequently asked questions in tech interviews.

Note: For understanding the fundamentals and main concepts of any topic I recommend GFG!

It includes solution of questions from:

  1. SPOJ - https://www.spoj.com/
  2. Leetcode- https://leetcode.com/
  3. HackerBlocks- https://hack.codingblocks.com/
  4. GFG- https://www.geeksforgeeks.org/

If you want to add Interview Questions of particular companies then you can make a PR and tag me. I will check that out.
