On yesterday's ABC363, SH00QiNan got the first place in a very-very short time. It's a new account and never competed before. Also, there's a CF account named SH00QiNan, which is also a completely new account.
Some of the gossips I heard as this account is controlled by six China NOI Silver player. (I don't believe) But even six best player can't solve problem so fast, I think.
It's Affiliation is QFLS. I'm not sure what QFLS is, but I am in Changsha, Hunan, China, and there is a school named Qingzhuhu Foreign Language School, but it's a nine-year-school (which means the students are 6~15 yo)
What do you know about this account, and what do you think?
Purr, out Tourist and JiangLY! The 1st place is stolen by this account!
Auto comment: topic has been updated by Amao_Fox (previous revision, new revision, compare).
Their order of answering questions is very suspicious, and it seems that each question takes about the same amount of time to solve, about 2-3 to 4 minutes. I think this strange result is a bit difficult for both humans and AI to achieve.
Maybe the problems were leaked?
A quick skim through the submissions shows at least three code styles (one with the comment on the top, one who uses
#define LL int, and one who usestypedef long long ll).I don't think it's impossible. If you give each person 1 problem each (except one doing A and B), ~21 minutes (the maximum time the account took for a problem) sounds doable.
A new chatGPT version is about to out
The CF account (SH00QiNan) actually did participate in yesterday's contest, and solved 6 problems (all but pF). However, the account was later marked unrated, so probably some admin knows about this. As Zanite mentioned, the different coding styles were also used on submissions of the CF account. With the suspicious order of submissions, it's pretty likely that it's a shared account.
