Solution: Remove All Adjacent Duplicates In String

Understand how to apply stack data structures to remove adjacent duplicates in a string. Learn to optimize your solution by iterating once over the string and using stack operations to remove pairs efficiently, improving time complexity from O(n²) to O(n). This lesson helps you implement and analyze a stack-based approach to solve duplicate removal problems effectively.

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:

  • 11 \leq string.length 103\leq 10^3
