What I found in my ROOM is that this user solved prob D with LLM, for I mean he directly submitted AI-generated code without thinking or debugging.
The funniest thing is that he had a Compile Error, which is related to non-ASCII AI-gen characters.
Let's watch his submissions: 342974921 342980027.
Well, though AI-gen codes are hard to tell and skip, I think there should be a basic AI-gen codes detecter, which can ban those obvious cheaters.
What's more, for today's contest, the unordered_map was hacked again. :33333
