Solution: Remove All Adjacent Duplicates In String

Explore an optimized approach to removing adjacent duplicate letters from a string by applying the stacks pattern. Learn to iterate through the string, pushing and popping characters on a stack to efficiently eliminate duplicates. Understand the time and space complexity of this linear solution and how stack operations simplify this problem.

Statement

You are given a string consisting of lowercase English letters. Repeatedly remove adjacent duplicate letters, one pair at a time. Both members of a pair of adjacent duplicate letters need to be removed.

Constraints:
