Yesterday I got a message that my submission (180621980) for problem 1748C - Zero-Sum Prefixes coincides with mod_07's submission (180638882). I admit they are kind of similar but it was just a simple problem and I think that much similarity is normal.
Weirdly my solutions aren't skipped after rejudging, (in fact I got another +187! Wow! message) but his solutions are. I can assure you I did not cheat and I did not supply him my codes. Mentioning MikeMirzayanov.
A div 2 contest contains hacking, so your code can be viewed by other people in your room, thus it can be easily leaked.
That's why your submission, which was earlier, wasn't skipped.
So the fact that you didn't supply mod_07 your codes can't say whether he cheated or not. Maybe we need some more confirmation from him.
i didn't cheat on this , why should i should on this, this was a simple problem , only our writing style were similar, and we thought in the same direction to solve the problem that was just a mere coincidence when thousands of participants gives a contest this may happen
True story broh, that's why in your template you have things like
that you completely forgot to use later
that's not really an evidence tbh. i too have like 100 lines of template, i haven't ever used half of what i copypasted
I do it too. Sometimes I automatically write long long instead of ll. You just have no time to remember that you have ll defined.
