New habit to share practice on Leetcode discuss

August 11, 2018

Introduction

It takes a village to raise a child.

It is time for me to build a good habit to share on Leetcode discuss.

One thing I can do is to share all my practice with leetcode discuss. I think that it is smart to share with others on Leetcode discuss, specially as a C# programmer. Since I learn so many things from other's ideas and also C# code, it is also interesting to see how I join the community and have some interaction with others.

My two weeks drill - 40 algorithm practice 

It was so exciting two weeks. It is the first time for me to write 40 algorithm on leetcode.com and submitted each algorithm at least once from July 10 to July 31.

I put all my practice in github folder. Here is the link.
