Leetcode 20: Valid Parentheses (I)

Dec. 18, 2017

Plan to review the algorithm called Valid Parentheses. It is the easy level algorithm. 

Last practice in 2016 is here. Another version is here. 

Here are the blogs I chose to study in January 2016, documented in a blog here:

Actionable Item

One thing I like to do is to break the blog written in January 2016 into multiple blogs, I may study a lot of hours on those algorithms. It is better for one blog for each algorithm. And also one blog for each good idea for Leetcode 20. 

Make life easy, specially learning algorithm should be more organized.
