Hi MikeMirzayanov,

My submissions were skipped from today's contest due to plagiarism checker for problem E2. As stated by others, problem E2 had a very similar idea to BOI 2022 communication, and the main logic of the code from my solution was copied from a previous submission for that problem (https://oj.uz/submission/592003, you can see that this code was submitted months before this contest).

I'm not sure whether this problem was intentionally copied or not — but I don't believe that I broke any Codeforces rules with this submission, since the source code was published before the contest started. Please review my case, thanks!

EDIT: My submission https://codeforces.com/contest/1746/submission/176378653

EDIT 2: In case evidence of search history cache is needed (my time zone is GMT-7, so 8:47 AM on October 15th is during the contest for me):
