Hi MikeMirzayanov, I've noticed a minor issue on the Codeforces. Sometimes, participants mistakenly resubmit solutions for problems they've already solved correctly, affecting their ratings. Could we add a warning pop-up before resubmitting solutions? It could prevent such errors and ensure fair evaluation. Thank you for considering this improvement.
The last time I resubmitted to a problem in a live contest thinking it was not submitted, I got a skipped verdict. Submission
see this was my solution of easy version which I first submitted — 254161720 then I submitted my hard version code mistakenly in easy version then it was considered and my previous one skipped — 254181450
