Solution: Remove All Adjacent Duplicates In String

Explore how to remove all adjacent duplicate letters from a string by applying the stacks pattern. Understand the stack-based approach that reduces time complexity to linear by iterating once through the string, and learn to implement solutions for string manipulation problems in coding interviews.

We'll cover the following...

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:

  • 1≤1 \leq string.length ≤103\leq 10^3
