My implementation of useful data structures, algorithms, as well as my solutions to programming puzzles.

This repository contains my implementation of useful data structures, algorithms, games, as well as my solutions to programming puzzles.

Each item is marked with a difficulty level. 1 - easy 2 - medium 3 - hard

If a file name starts with 'lc', it's a problem from leetcode.com - Super convenient because I am too lazy to write hundreds of test cases to validate the code :)

Written in python3. Thanks Chip Huyen (@chiphuyen) for the inspiration.
