When your code is wrong, the server gives you a clue hinting at what's wrong in the original code.

It doesn't know what's wrong in the code you submitted... it is not understanding deeply what's wrong with your code. It's not some huge multi-terabyte language model analyzing arbitrary code, or whatever.

It just knows your code is wrong and gives you a clue so you can try again.
