Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.

This isn't my answer. I don't know what you're talking about, and I suspect you don't either.
Why did you think this was an LLM generated response in the first place? If it was the comments: commenting your code is normally a good idea, but that doesn't automagically mean it's LLM generated.
While you're correct that a set is a mistake in this case (as well as caring about performance in general, unless specifically required), your snark at the end about the LLMs is weird. This solution is older than ChatGPT.
Yes. Obviously you read the wrong test case.
no idea since you don't give the entire list. Advise: don't forget diagonals and segments of more than 4 tiles (when connecting 2 tils + 3 tiles, adding one in between them, for example)
nope
