Hey. Anybody suspect cheating in the April Long challenge (APRIL22D) Div 4? Until last night, the last question of the contest had only 5 submissions with accuracy of 0.47. This morning, it has already gathered over 100+ submissions and almost all of them seem to be from one institute(which i will not name but is open for anybody to go see for themselves in the contest rank) . I think it is a little fishy and event organisers should look into this. Also i don’t know if this is the right place to raise this issue but i have mailed to plagiarism@codechef.com as well but since the contest ends in just a few hours, i wanted to get it looked into asap.

after April long challenge ended I tried to check for soln to questions I couldn’t solve… and to my surprise, every solution I clicked to open was identically the same. and I don’t know if they are robots or how their minds work in such a similar fashion. Its a mystery for me now, hope someone can enlighten me why I can think like them and solve the problem in such an identical manner.

Hey. I posted a message just before yours and there are over 100+ students from the same university with exact same code as you pointed out. Hope actions are taken against them

bro even I didn’t solved it my rank was 10 and when I checked after 2 pm in just 1 hour my rank went straight to 48 i was troubled by the minmax problem but seriously what is the point of cheating . its really hurts when someone just leaks the solutions long challenges are like a marathon meant to train our brains for the short ones but novice programmers tend to overlook that small detail and commit these things . i can understand it takes a whole day to figure out some corner cases and then suddenly whiplash and 50 similar submissions in just few minutes…it really breaks the moral…

yeah sure… so basically whenever you come across people whom you think have cheated in contest, You need to post their submissions here itself or you can mail it to codechef help id they will surely take the necessary action .Nowadays codechef plag check has become good so most of the cheaters fall into their radar.
Here are some of the few codes which I have found to be totally same but their rating is not deducted. These people have submitted the last problem exactly the same or have changed the variables only, so that they can achieve global rank 1 in the contests.

Due to these kinds of people our rating gets affected very much. So, I request you to give a penalty of 275 points as soon as possible or permanently delete their account if they indulge in many such cases.
now, you really have to do something . in june lunchtime codes were leaked on youtube. in every contest, codes leaked on youtube and telegram. and as a result , users who give contest honestly , get demotivated , and yes there is rank which suddenly drops after leak and rating decreases. please codechef, do something.

I was wrongly charged with Plagiarism in Starters41. Upon appeal, It was acknowledged that it was a false positive.
A week has passed, The Plag mark is not gone from my profile, Rating has not been reverted
These two people cheated in STARTERS 56
Please take action on them.

Yes its truly heartbreaking to see such videos on social media platforms openly providing codes and eventually lowering moral of honest coders. Codechef must improve their algorithm to catch plagarism.
This user has been cheating regularly in the codechef contests and here is an instance of it from starters 68
https://www.codechef.com/viewsolution/81950205
This code has been copied word to word from
even the variable names are same and only the last bit of solution function is changed.
This is clearly plagiarism and his account should be banned or demoted.

Great! That’s quite amazing. It gives me an intuitive picture of how much time I’ve spent on each application.
But moreover, how can it help me to be more focused? Like I’ve realized that there are a lot of switches that break my focus.

There are multiple candidates I found with similar name, who posted exact same code on telegram and also submitted on codechef.

@admin , @iceknight1093 ,
There should be one script written, which will take codes from telegram chats, and try to plagiarise against codes of submissions.

Please use the plagiarism thread or send an email to the id given there for reporting people (also I have nothing to do with plag checking, no point in pinging me).
Hey @drexdelta my submission is considered as wrong answer not accepted for nopalindrome
I solved only one question on div2 check it plz remove it
you were actively seeking for solutions through out the contest. You get plagiarised for wrong submissions as well. Not just correct submissions. If you think that you didn’t anything wrong during the contest, then I got no words for you.
bipanshukumar and ashnub425 have been perma banned.

Thanks for reporting btw @drexdelta
It really helps to uproot the cheaters, and build a healthier coding environment and coding culture. Your efforts are highly appriciated.
Thank You
