I thought that it was an interesting bug, since one change far away broke something which seemed largely unrelated, and even though the code is self-evidently wrong, it's still fairly difficult to find the bug if you don't have some hints.
This is almost ancient Greek for me.
I now do understand why people have been studying Computer Science for Years, and it is not possible to rely entirely on Chat GPT prompting like I usually do when dealing with code bugs.
Computer science is a broad course, i wonder if anyone can become a perfect computer scientist since it will involve making deep researches about coding and programming errors that occurs abruptly.
OH yeah, ChatGPT can ONLY help is solving some minor code bugs while it requires real technical knowledge to handle intense coding Bugs
