Need Help with a Coding Challenge Involving Square Strings

It seems like you need to start by breaking down the problem into smaller parts. First, understand what square strings are and how you can identify them in your string S. Make sure to implement a function to check for these patterns. You’ll also need to think about how to efficiently remove these square strings from S to try and reach an empty string. Try writing out the steps you’ll take, and feel free to share your code if you need specific help!

First off, make sure you fully grasp how to generate the cyclic shifts of "COW". Once that’s clear, focus on efficiently checking all possible square strings within S. Given the constraints, think about using a stack or other data structures to handle removals. And don’t forget to test your logic with different scenarios to validate your outputs!

If you're stuck on the logic for the algorithm, try breaking the string into segments and analyzing those segments individually before trying to combine them back. Use examples directly related to your test cases to visually confirm your algorithm works as expected! If you post a snippet of your code, that could help others provide more targeted advice.
