Solution: Minimum String Length After Removing Substrings
Explore how to apply a stack-based approach to remove all occurrences of 'AB' and 'CD' substrings from a given string. Learn to implement the solution that iteratively processes characters and efficiently manages pairs to return the minimum string length after all possible removals.

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.
Constraints:
