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.
