Data Structure and Algorithmic Problems solved in many languages

This repository is inspired by keon's solved problems in Python 3. I wanted to compare solutions across different languages and learn them in the process. Solutions may be my own, from keon's repo (mainly the unchecked python ones) or shamelessly stolen from the internet.
