Minimum String Length After Removing Substrings
Understand how to efficiently reduce a string by removing all occurrences of the substrings AB and CD. This lesson guides you through using stack-based logic to simulate removals and achieve the shortest possible string length after applying all operations.

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, ...
