In Codeforces Round 958 (Div. 2) round ,in official standing you can clearly see that I have completed Problem B in just 12 minutes and the warning message/mail sent by system contains such participants who has mostly lower than my rating and they have submitted code after my submission .And I am 100% sure that this is someone from the same room who have leaked my code .I think that Codeforces should add some features such that participants in same room can not leak the code of other after submitting it .
This is my room in which I was assigned during contest.
I hope that Codeforces team and MikeMirzayanov will look into this and try to resolve the problem of leakage of codes in same room by either removing hacking feature or something else by which other participant in the room can't copy the code...

Wait you can see codes of people who not locked their problems?
If you have submitted the code with verdict pretest passed then you can see the code of participants of that problem in your room
But you can do this after you lock the problem
It wouldn't be possible to show code while making it impossible to leak it. Hacking is also an essential part of contests because it allows people to create test cases that the problem writers didn't originally think of (even though it is less common nowadays). There is no truly impassable way to fix this
Actually, I think Codeforces might add a hacking phase just like div 3 or educational rounds.
I think people using hack feature to leak your solution is a far greater concern currently than hacks as the number of rounds in which a lot of hacking happens during contest time is quite low
I strongly agree with this suggestion.
did your soltuion got skipped ?
No. Others who submitted my code their solution got skipped I just got warning message.
I don't know what the f__k is inside their brains, the cheaters.
They just lock their problems, open the hack tab and then OCR someone else's code to leak?
How evil, you can leak some random guy's code, blame some random guy and (maybe) make him skipped?
Hack phase need to be added on every Div.
