User C2024liuhongyi use 2 minutes to AC A to D,I thought it was impossible,and I found him cheating.
In the latest contest (Codeforces Round 903 (Div. 3)), the codes of the problems DEF of C2024liuhongyi are very similar to those of Complete_Reality.
C:
D:
As you can see,although C2024liuhongyi's code just has 3 lines,their code are the same.So I think they are the same user and their submissions should be skipped.
Although C2024liuhongyi is Unrated,it's not an excuse.In my opinion,he shouldn't use 2 IDs to join in the contest and cheat in it.
