MikeMirzayanov, I believe I have been falsely accused of plagiarism in the recent contest. My solution matches a publicly available code from GeeksforGeeks that was published before the contest. Could you please review my case? Here are the details:
- Contest ID: 1983
- Problem ID: 1983D
- My solution: 269278403
- Matched solution: 269258951
- Public code reference: GeekForGeeks Link
-Description: In last div2, My solution https://mirror.codeforces.com/contest/1983/submission/269278403 got skipped telling in has significant match with https://mirror.codeforces.com/contest/1983/submission/269258951 this solution. But the two functions minSwapsToSort() and minSwapToMakeArraySame() was copied from geekforgeeks https://www.geeksforgeeks.org/minimum-swaps-to-make-two-array-identical/ . Our main functions are even different. Hope codeforces will take steps as soon as possible.
New to Codeforces, is it allowed to use codes from other sources?
https://mirror.codeforces.com/blog/entry/8790
Word of advice — just ask GPT to write the code for functions like minSwapsToSort() instead. Then your code will at least not be identical to a load of other people's. But yeah this highlights an issue with CF's cheat detection.
Thanks, i'll do that next time.
bro ofc you will get skipped because 80% of your code matches. you will get skipped even if u have same code but different variable names. your both 2 functions matches exactly so it was supposed to get skipped. u should have written your own instead of just copy pasting. noting to fix from codeforces side
Thanks for your opinion. I threw it in the dustbin.
threw*
No doubt you're from India
okay so? why does that matter? did i say anything about you or your country? i just corrected you mate. me being from India makes no difference
You don't need to correct others' grammar when the topic is not "English Grammar." Your first comment was baseless as it doesn't go against the third-party code rule of CF (even if the code is 100% from GFG). Hope you understand, I have no problem with your country; just remembered another guy from India also tried to fix my grammar when the topic was "Biden is good or bad." Sorry for that. Thanks.
Even GFG is Indian...
That doesn't change the fact that indians are telegram cheaters
Your statement in logically invalid. Majority of Indian CF accounts are not cheaters, even though I do agree most of the cheaters are Indians. You would benefit from reading academics rather than giving hate speech about other ethnicities on online platforms meant for healthy competition.
Competition will be very healthy when cf removes users like butterpaneer, for saying nonsense things in post. Also removing indians was just a joke, I donno why India even give birth to people like butterpaneer who comments baseless things on a post. I admit it's not fault of India, but butterpaneer's. But India should be aware before producing people like him.
what did i even do to you bro? stop attacking me personally, i never said something personal to you, if you cant even take a joke about me correcting your "throwed" then idk what man. also how come correcting someone is wrong, you should have ignored it anw.you are unnecessarily milking it more and more now. if you do not agree with me thats fine and i accepted that, but the stuff you are saying now is just personal hate. i dont think thats healthy for codeforces either. its just pure irony how you are stating the above. stop making stupid and hate statement just to keep your post relevant, anw i am not gonna reply anymore after this, have a great day and good luck.
I am talking about your first comment, not the spelling one. And yes you should leave, leave cf forever maybe.
say ArefiX is mentally retarded does that imply all users on cf are mentally retarded
Yes that implies, as you are the people who keep this thread alive. All could have never happened if someone didn't write "bro ofc you will get skipped...(bla bla bla)"
Also the biggest cf cheater groups are from India, cf should ban India for some months.
Not sure why you are getting downvoted for stating the truth. As an Indian myself, I hate to admit that the majority of cheaters originate from India, and I too am beginning to think that Indian participants should be banned for a few months. It will be hugely unfair to the honest participants, but it will be in the best interest of this platform and the coding community.
Why do you want to ban yourself? I certainly wanna keep participating in contests. Just banning all Indians is definitely not a valid solution.
When you are honest nothing really matters, though biggest groups are from India, but there are many legit talents from India too. I just commented so cheaters send my comment's link to there group and downvote bombing starts, I really enjoyed this. All the best, remember when you are honest, nothing matters.
Cheaters aren't downvoting ... Re-read the statements you are writing, you will know the reason for being downvoted.
Yes this post was shared in cheater's groups, and they downvoted. Next time India should think again before giving birth to people like butterpaneer, I don't have any issue with India, but this indian user.
Why would you even bring up the fact that butterpaneer is Indian then? And then somehow you go from not having any issue with India to:
You really think people will believe you when you say you have no issue with India?
"You really think people will believe", hey do you really think I care what 'people will believe'?
yes, of course you do!
Just a reminder that in Codeforces, you are, in fact, allowed to use code that is online prior to the contest!
okay mb but i think its really hard for codeforces to know if something was posted somewhere before the contest and both have used the same sources or no, it will be hard to determine which is cheating and which is not
I think it's pretty obvious in this case because GeeksForGeeks is a well-known and widely-used site for people learning DSA. However, again, this is why I said it's probably better just to get GPT to generate you the code because then it won't match anything online identically in most cases.
Leaked solutions for the problem might also use the same blog
You are allowed to use codes which were online before the contest starts!
Hmm my code's source:https://www.geeksforgeeks.org/minimum-swaps-to-make-two-array-identical/ it was uploaded 19 September,2023. Still cf skipped my solution.
Yes, you deserve justice.
Hi, I was the author of the other submission. I don't know you, I did not share any solutions, and I am 100% sure that you did not intend anything malicious. I think this is a flaw on codeforces side, as this problem can just be solved by pasting in from gfg, and due to the problem not requiring you to write a lot of code, our logic coincided. Hopefully codeforces admins see this and revert your status. As a previous comment said earlier, GPT may help in avoiding situations like this again, but it is definitely allowed to use code from online sources like gfg (don't waste your time rewriting the code from scratch).
Thanks for commenting here, also Congratulations on becoming CM. Hope admin removes the flag.
It is still smart to remove comments and change it to your style though. That is what I do if I look at pre-written code. That takes very little time, and it prevents yourself from being skipped. (at least I think)
Unfortunately, I don't think removing comments and changing variable names does anything, as the plagiarism detector looks at how the code runs, and not how it looks, so you would have to recode some parts in order to pass the check that way.
That is true. I usually just have the function from just say geeksforgeeks as a function in my code and then recode it in my style and how I would code it, and just delete the geeksforgeeks function. It seems to work for me.
Write a mail to MikeMirzayanov. He will surely check and will remove that flag if found non-punishable.
I also used a code snippet from gfg , luckily I didnt got skipped : https://mirror.codeforces.com/contest/1983/submission/269250099
The same thing happened to me as well. I have tried to contact the CF team for two days, but there is no reply. If anyone knows any other way to contact them please do tell.
I'm also trying to contact but MikeMirzayanov is very busy I think, misjudgement should be solved fast.
I think there should be a codeforces support system since it's not fair to those whose appeals get overlooked.
We cannot demand that as it's a free website, but if cf does this, that would be great.
