So i was just going through all subs of problem C for trying hacks and found some highly similar submissions made during contest time.

Same code with just variable names altered, and covered by a lot of unused boilerplate code possibly to escape detector? I think it is a case of plagiarism. I have not seen their codes of other problems, so there might be something of interest there as well.

MikeMirzayanov Please look into this and take necessary action.

I feel like you should investigate a bit more, because it seems to be that the code is quite short, so it might be a coincidence.

    Same coding style with code written in same order by people from the same college. I think something is definitely wrong here.

      PS I am not anyone in the above three So let me mention one thing. I learned dp from my friend and we both now use to write recursive dp with almost same variable almost same return condition ... doesnt mean we cheat .. dp is something i think most of them write in common way .. so its not always abouyt cheating ... sometimes u get good friends with whom u can learn

        I second this. I learned from my senior's code and we now write almost the same code for easy recursive dp solution.

      It's probably not worth jumping into this discussion but I'm going to anyways.

      There is certainly a possibility that these three people are cheating and I agree with your original post asking Mike to "look into this and take necessary action". But now you seem to be making an indirect accusation of cheating, which is jumping to conclusions rather quickly.

      The code is not the same, although it is similar. If these three are friends, and they learned DP in the same style, of course their codes will look similar. I'm not saying they definitely didn't cheat, just that this isn't enough to prove anything. Your point about unused boilerplate code is, in my opinion, also invalid. Although I think large excessive templates are stupid, many people use put them in their programs and never use them. I've seen people put in a template for everything from Dijkstra to FFT to Segment Tree. Just having an unused template doesn't suddenly mean you're trying to circumvent a plagiarism check.

      That being said, it is probably worth looking further into this. But I don't think we can draw any strong conclusions just yet.

    Salle bsdk have some respect okay. The code for this problem is very same anyway and I am sure these people don't need to cheat since they are good coders anyway. Bhosideke tu lodu hai grey coder.

Before commenting investigate properly it was standard dp problem and anyone with the iterative approach would write a similar code. Going by your logic the tutorial was also similar then the tutorial also cheated from us.

Hey, I guess you are trying to be too smart by opening an account only 3 days ago and creating a fuss of a blog to gain popularity. You are too mean dude.

And talking of the similarity of codes, it's absolutely my choice, which template I shall use and I am not gonna look at each and every other participants template (even though they can belong to my collage) . And for this simple dp solution, how can you draw the conclusion that there is a case of plagiarism. There is enough to distinguish them.

Instead of all these, try solving the question yourself, spend time in problem solving and take part in contests. All the best bro.
