UPD 1: The issue has been resolved. Thanks to the Codeforces team for looking into it.
Hello Codeforces team,
I noticed an unexpected submission in my account's submission history and wanted to report it in case there is an issue with the system.
There is a submission for A — Monocarp's Contest dated September 22, 2026 at 15:27, which appears under my account.
However, I did not submit this solution, and I did not make any submissions at all on September 22.
Could you please check the logs for this submission and see how it ended up on my account?
I wanted to report it as soon as I noticed it, in case this is affecting other users as well.
Submission: 391645045
Thank you for looking into this.
