Solution: Minimum String Length After Removing Substrings
Explore how to use a stack algorithm to remove 'AB' and 'CD' substrings from a string to achieve its shortest length. This lesson helps you understand stack operations to solve string manipulation problems efficiently and prepare for related coding interview questions.

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:
