Today, I've received system messages that my submissions on problem A and C from last division 2 round (round #738) coincides with someone else, and got all my submissions skipped.

I compete on sublime text, and do not use any online editors such as ideone.

I'm guessing the reason my submissions got flagged is due to how simple solutions to problem A and C are.

These two are the submissions to problem A which the system thinks coincide. 125936660 125936386

Comparing them with the codes from the editorial and jiangly, they're almost similar to our codes. I think most people came up with a similar approach, so these similarities cannot be an evidence that we cheated. Editorial 125934926

It's the same for the problem C. These are the submissions flagged by the system. 125952554 125957871

And these are the codes from the editorial and Maksim1744. We can again notice the similarities on all 4 of these codes. Editorial 125939776

Here are some other reasons I couldn't have been involved in a cheating.

• The round is unrated for me

• Even though I solved E at the 69 minutes mark, duchung has no submission on the problem. If he wanted to cheat for his rating, he would have copied my E submission as well.

• I got AC on problem A at 3 minutes, C at 22 minutes. Meanwhile, duchung got A accepted at 3 minutes and got one WA on C at 23 minutes, into AC at 27 minutes. There weren't enough time for duchung to modify my code and submit.

Therefore, I ask MikeMirzayanov and other codeforces admins to kindly revert the skipped judgement on my submissions.
