Maybe it's just a coincide.If I do wrong,sorry for it.
Hey guys!I find something strange in the last contest.xay5421 solved E in 10 mins.
When I see his code, I find:
// author: xay5421 // created: Fri Nov 12 14:55:34 2021
The created time is very strange,you can see the difference: (problem B):
// author: xay5421 // created: Sun Nov 14 14:09:02 2021
And then, I also notice his code of D:
// author: xay5421 // created: Fri Nov 12 14:20:34 2021
Very strange,right?It seems someone is manage to help with him,but he/she forgets to modify the created time.
Then,I search past contests and find something even more strange:
- in CF1601,D 0:59,E 1:09.
- in CF1586,his code of G is tab with 8 spaces,but other codes is tab with 4 spaces.How did he do that?
- in CF1553,E 1:07,I 1:20,H 1:47,G 2:24, F 2:29. Is he a superman?
- in CF1545,he submits a Compilation Error code.link.U can see "#include<bits/甩头dc++.h>" in this code.
And also,raingirl, xuanyi are his accounts(maybe more).Why does xay5421 use so many accounts?
As a participant,I'm coufused how does he do that.Is there any LGM help him to make it?
