Leetcode 10: regular expression matching

Dec. 29, 2017

Introduction

It is so interesting for me to learn Leetcode these days. I work on mock interview continuously on those 30 algorithms. And today I reviewed Leetcode 18: 4 sum last 5 practice, and then I tried to get organized and reviewed the past practice, and then found this young graduate software engineer working in facebook, I start to code review his post on each Leetcode algorithm.

Code review

Leetcode 10 algorithm blog is here.

Here is the gist I created for the study. I will play this code and write a C# and figure out how it is.
