Alice and Bob are too smart so called coders.They have now figured out how to escape from Plagiarism. Mayank is struggling with with Plagiarism on codeforces now he wants to figure it out if his two friends Alice and Bob have applied the rule to avoid Plagiarism.

They can perform two type of operations.

  1. Change the variable names to any other lowercase Latin letters.

  2. Insert lot of commented code.

Sample test case:

Alice submission->link

Bob submission->link

Alice submission->link

Bob submission->link

Please Upvote if they followed the rule.

Note-I was wondering why the submission of same problem during contest of both players have not exceeded 10 minutes.

For more test cases open their respective profiles.

Nice, they teach us so many ways to cheat and How not to actually learn (They are born talented, this requires a lot of learning. I salute to these guys, :salute) If anyone else also wants to learn some more hidden ways, you can find in this guy's contests submissions https://codeforces.com/profile/YashAryan YashAryan

This is too much. At least pay some respect for problems A and B. You can do that by yourself.

    If people start to solve A, B by own then the telegram solution selling market would die. Cuz cheaters are only able to solve those 2 problems in contest :holyfuck:

    Why does it matter to you if someone cheats? And you don't have the guts to comment from ur main account. I wonder why.

      Well let's have a scenario you are playing your favorite game (CS GO) to relax. You queue into a match and start playing. The next thing you know someone is cheating and has spoiled at least that match for you. The cheater while cheating has wasted your time and due to this your interest in the game drops. Similar is the case with these cp cheaters.

      Edit: Just realized that the accused nitin_05 has changed his org name. What kind of morals does this person have . He has been accused and instead of removing his previous org name from account. He has put a new one in place , defaming the new org. My request to you nitin_05 , please remove the college name from yours codeforces id. If you want this to prevent people from getting to your linkedin ID just know that it's trash af and worth no one 's time.

        Well, csgo is entirely different scenario cuz in that I am directly affected. In codefoces, it doesn't matter to me if anyone is cheating, since it doesn't affect me in any way.

          Cheating affects each and every participant of a contest. Just read about how rating mechanism works and you will know.

            Well, it doesn't affect me atleast since I don't care where the rating goes.I believe it's the same for many.

I find it very suspicious that an alternative account was able to randomly identify such an Alice and Bob. Do you all go to the same school or something? Can you please keep the drama to yourselves? Yes, the plagiarism checker is kind of outdated, but that doesn't give you the right to openly attack each other (when calari could have posted links to code snippets, or cropped out photos instead of the submissions themselves)

    You seem to be one of those.
    1. No we don't go to same school.
    2. You can also keep this drama to yourself.
    3. who gave you the right to comment in this blog.
    And about alternate account, people from cheaters community keep on messaging wrong things and we can't report them.

      obviously you did something that even computer can't do. But I was really wondering how a human can actually find out two exact same solution out of thousands contests and 1000s submissions. If we even do brute force it is quite hard for a human. themadprogramer's comment has point too.

        But I was really wondering how a human can actually find out two exact same solution out of thousands contests and 1000s submissions.

        Just repeatedly picking random pairs of contestants and taking a look at their solutions will eventually lead to discovering a pair of suspected cheaters: https://en.wikipedia.org/wiki/Infinite_monkey_theorem

        I'm not surprised to see such cheater discovery blogs popping up from time to time. But the main problem is that this method of searching for cheaters doesn't scale and can't catch them all, while wasting an enormous amount of man hours. The only positive aspect is that the cheaters can never feel safe even after fooling the automated plagiarism checker.

          but I was also wondering does it really matters rating and all?? Noo... real problem solver does CP because they enjoyes it not because he/she wants to rank anyhow.

    Your argument is senseless. And why do YOU want to protect the cheaters??

    Can you please keep the drama to yourselves?

    He can post whatever he wants. Grow up, don't be stupid and an a**hole.

Being an Indian myself, I am really ashamed of what the CP community has been made by us because of some bhaiya saying so so rating gives a job at FAANG. This problem of plag and sharing solutions during contests is even more profound in Codechef Its not even worth giving contest anymore in platforms like Codechef
