So I used AI in last contest,
at the time I believed It's allowed in the rules, now I'm not so sure.
after reading AI rules, I didn't find specifics for my case.

at 2122C - Manhattan Pairs, I didn't know what is a disjoint pairs.
So I typed "disjoint pairs" in chatgpt, not a single other words.
and if I typed the same thing at Google the new AI thingy also give more or less the same response.

I believe this is a fair use of AI, nevertheless if the rules says otherwise I will comply.
