This repository contains all the solved problems taught in Smart Interviews Data Structures and Algorithms course. Have a look at the website: https://smartinterviews.in/
Problems: https://www.hackerrank.com/contests/smart-interviews/challenges
Curated list of problems which can only be solved when you clearly understand the topic. Nice problemset!
If you wish to take this course then I recommend to book 2 months in advance because there is a huge crowd coming these days
