LeetCode ProblemResulting String After Adjacent Removals
You are given a string s consisting of lowercase English letters. You must repeatedly perform the following operation while the string s has at least two consecutive characters: Return the resulting string after no more operations can be performed. Note: Consider the alphabet as circular, thus 'a' and 'z' are consecutive.
