Leetcode and Projecteuler

Recently I have found or say re-discovered the fun of programming, so I started working on leetcode problems and also working on solving problems at projecteuler, both are quite interesting sites.

I will post the solutions later on this blog. Maybe daily or less often, based on my spare time.

The solution code can also be found here: https://github.com/stanley-shi/learning/tree/master/leetcode
