Hello everyone, I have been told by my friend that many students from their institute are involved in cheating on many contests of Codeforces and CodeChef and many of them have been plagiarised on Codechef. So I check codes of top-ranking students from the last contest i.e. Codeforces Round #652 (Div 2) and found that 3 of them have same code with a different basic template and different variable names and in some cases, they had unnecessary loops in their codes (which are of no use), I think they had done so that they can't be caught. Please MikeMirzayanov takes some strict actions against them.

here's the link of first-person code — https://codeforces.me/contest/1369/submission/84770782 here's the link of second person code — https://codeforces.me/contest/1369/submission/84775423 here's the link of third-person code — https://codeforces.me/contest/1369/submission/84779461

This is not just the single case, you can found that these 3 persons have done cheating in different problems also even the code of problem C is also same, even 2 out of 3 have same comments too, they are too busy in cheating that they forget to delete the comment. here's the link to the code- https://codeforces.me/contest/1369/submission/84790316, https://codeforces.me/contest/1369/submission/84793909, https://codeforces.me/contest/1369/submission/84794125,

here's the link to their problem D code- https://codeforces.me/contest/1369/submission/84807657, https://codeforces.me/contest/1369/submission/84801337, https://codeforces.me/contest/1369/submission/84808172.
