1787-C leaked on YT during contest
By bajelega, 2 months ago, In English

When will the plagiarism check run? In TypeDB's round, 1787-C, Remove brackets was leaked on youtube and many cheaters did it disrupting the standings.

UPD: I don't cheat. Cheat is a dishonor! I just found the problem name on a youtube channel a day after the contest! And this is unfair harming fair contestants. I hope plag check is run soon so those cheaters are skipped. And I won't say the name of the channel so it is not an advertisement. Please, upvote so admins skip cheaters and standings become better!

UPD2: Why was this post unpublished and moved to drafts? What did it violate? Also, did the round become unrated? I see plag check done, but there is yet very similar C solutions not skipped.

    How much would your rating really change by these cheaters? I feel like most of the time it's cope. Think I would've lost delta regardless of cheaters last round

    Well, your solution 191154288 have the exact same structure (except some variables/arrays renames) to these submissions: 191151588, 191153282, 191150426 or 191139412. And literally half the C skipped submissions I checked were suspiciously similar... Sometimes is better to admit your mistakes...

        controversial opinion: i don't actually care if you cheat on the contest it's your life (though it does annoy me a little cause you deflate my positive deltas and inflate my negative deltas). However, I don't think solving 1200-1300 rating problems consistently would give you a high probability of solving this div2 C. Granted I won't claim that you cheated or didn't cheat. Meanwhile i'm crying cause I submitted my sol in pypy and got TLE after system tests but identical code works when submitted with pypy-64.

      With this standard of plagiarism detection, you would get a lot of false positives every contest, I don't think its reasonable to expect for everyone to have different base cases and transitions in their dp, when over 1000 people solved it.

      I don't know much about how code similarity is measured and the expected differences, so I may be wrong.

        tell us that why you write porvector insted of writing dp. is it make any sense? if any good programmer who actually solve problem in contest with dp, will always write dp.

        you changed variable name from others code , now everyone knows you cheated.

            no one is fool. While coding no one thinks about getting plagiarized. Explain these lame excuses to those who have never coded in their life. You are a cheater.

            Your logic is riddled with mistakes.
            First of all, what the hell even is porvector?
            Second, what an "accident" of how it collided exactly. porvector to me just sounds like some random name, but yet you wrote the exact same random thing in your code. what a coincidence, eh? Why would you bother to write something as long as "porvector" when you could've written "g" or "f" or something shorter when you're just writing some sorta random name?

      I guess you might have taken this otherwise, striver is on youtube and he has taught dp and has a playlist, I think this guy is referring to a video from which he got the idea I guess

    Your code is very much the same compared to this video https://www.youtube.com/watch?v=4sVV35vlBQQ. The video leaked the C solution and it seems like all you changed is the variable names

    Also, this isn't the first contest where your code is skipped

Not only in this contest, but some cheated in CF Round # 847 Div. 3, instead of individual participation, some exactly copy paste the code.

I request Vladosiya and other Codeforces authorities to check plag. even though it is a Div. 3 contest.
