Statement
Given a string s consisting solely of the characters '(' and ')', determine the length of the longest valid (well-formed) parentheses substring contained within s.
A valid parentheses substring is one in which every opening parenthesis '(' has a corresponding closing parenthesis ')', and the pairs are properly nested.
Constraints:
