/*
Given a string containing just the characters '(' and ')', find the length of the longest valid (well-formed) parentheses substring.

For "(()", the longest valid parentheses substring is "()", which has length = 2.

Another example is ")()())", where the longest valid parentheses substring is "()()", which has length = 4.

Algorithm time complexity is O(n), and space complexity is O(n)
Basic algrithm is to keep track of the longest matched paramthesis.
But we need to separate the valid substring, which have 2 special cases: ())()() and ()()(((), and others(whole string
