It is the first time I plan to spend time to study the solution one by one. The blog is the third popular post on my blog. I wonder a few times, and today I did look into a few solutions, such as Leetcode 10: regular expression matching, binary index tree, and I do find that the leetcode solutions are excellent, I should spend time to read those solutions in 2018.
