Yo↵
So apparently I found out this [user:marshadow_ninja,2025-06-13] guy and he gain my suspicion through his code.↵
↵
Problem A: "Okey normal dude coding yeah yeah"↵
↵
https://mirror.codeforces.com/contest/2118/submission/324059526↵
↵
Problem B: Instant change of coding style, using T instead of tt as his previous A submission, variable name starts to get longer. Also this style is very VERY similar to ChatGPT↵
↵
https://mirror.codeforces.com/contest/2118/submission/324084308↵
↵
Problem C: "onesAbove" array, interesting name tbh. Also the logic and style is the similar to ChatGPT↵
↵
https://mirror.codeforces.com/contest/2118/submission/324094098↵
↵
Problem D1: He did this BEFORE C, how good is he? Same style as ChatGPT, as usual↵
↵
https://mirror.codeforces.com/contest/2118/submission/324091690↵
↵
(using THIS↵
↵
~~~~~↵
auto state_id = [&](int i, int dir, int r){return (i*2 + dir) * k + r;};↵
~~~~~↵
↵
is what ChatGPT would do, yes i know there ARE people use this, but ChatGPT usually use this too, I'm just bringing up the issue.)↵
↵
Problem E: Hmmm looks much more legit than the others, but his sorting method is just strange, usually people will create a bool function. Anyway still look ChatGPT.↵
↵

↵
Can't forget to tell you about his massive leap in rating. Bro just INSTANTLY jump to specialist after 4 contest. Almost every problem look sus and not hand-written, As you can see in his submissions (He only submit for contest only so its easy to tell)↵

↵
Just look at it and tell me your opinion↵
↵
EDIT: His submissions have a lot of strange and long and "meaningful" variable name.↵
↵
EDIT 2:↵
↵
Here's my friend [user:Defylogicguy,2025-06-13]'s opinion about this↵
↵
Look, he solved D1 in 44 minutes, C in 47 minutes. How can a person solved 2 problems in 3 minutes. Plus naming long variables takes a long time. And omg, constructing a struct for each testcases, nobodies that dumb. Plus in E, he's using: using pii = pair<int, int> while he doesn't use and it's not even a snippet. For those who don't know, it's the first time I have seen a function named llabs(), I have been into CP for a year now and haven't seen llabs() before. He even use different snippet for each code
