https://leetcode.com/problems/longest-nice-substring/description/A string s is nice if, for every letter of the alphabet that s contains, it appears both in uppercase and lowercase. For example, "abABB" is nice because 'A' and 'a' appear, and 'B' and 'b' appear. However, "abA" is not because 'b' appears, but 'B' does not.Given a string s, return the longest substring of s that is nice. If there ..
