- sharmasapna/Leetcode_Solutions: Python solution to beginners questions

Python solution to Leetcode Questions.
This is a very good platform to learn best practices of python coding.
I am compiling solutions to some questions as I solve and have tried to include as many comments as possible for easy understanding.
(Tip: The best way I think is to print and see what exactly is being executed !)
Just keep Practicing !
