Solution: Minimum String Length After Removing Substrings
Understand how to apply stack data structures to iteratively remove specific substrings from a string. This lesson guides you through recognizing and removing 'AB' and 'CD' pairs to find the minimal string length, using a linear time and space algorithm.

Statement
You are given a string, s, containing only uppercase English letters. You can perform operations on this string where, in each operation, you remove any occurrence of the substrings "AB" or "CD" from s.
Your task is to return the shortest string length after applying all possible operations.
Note: After each removal, the string joins back together, potentially creating new occurrences of "AB" or "CD" that can also be removed.
