It’s saddening!
Plagiarism should be stopped.

The Source of the plagiarised codes seem to be from this user, https://www.codechef.com/users/simplecoder_07

I found a bunch of people from the same college copying the exact code from a youtube video with the solution in it. The video was published during the contest

ARRFILL (Only difference is the capitalization of variables)
thelordsaurabh - CodeChef: Practical coding for everyone
mayank_46 - CodeChef: Practical coding for everyone
ravish_29 - CodeChef: Practical coding for everyone

The video they copied from : - YouTube
( Kindly note that the link is set in such a way that it takes you to a specific time when opened. I have done this so that you wouldn’t have to go through the whole video to search for the code)

Two of them have the exact same code for CHARGE as well
thelordsaurabh - CodeChef: Practical coding for everyone
mayank_46 - CodeChef: Practical coding for everyone

Please look into this as they have boosted their rating to the mid-3 star level because of this malpractice, I have sent help@codechef.com a mail as well.
Thank you

Most of the submissions for CLOSCHEF and CLEARRR in the last hour are identical. Hope @admin will do plag checks before rating updation.

gamma30 · August 22, 2021, 7:30pm

is plag check even a thing here on codechef?

punitive_1729 · August 22, 2021, 7:37pm

They dont try to even solve it themselves. Solved everything in 1 hour. Shameful @riyaa_03. Submitted 4 of the hardest from the contest in under 15mins.

tejaswarambhe · August 22, 2021, 7:49pm

has that happened before ?

gamma30 · August 22, 2021, 7:27pm

CookOff Div 2, Q4) Clear the array

And so on. I stopped looking at page 6 out of 128. 9/10 submissions that i opened contained the same code.

Now i know that a 5/6/7 start coder would come, copy paste the same thing that they say in every other plagiarism report post i.e “ignore them and focus on yourself”.

I know I know, but hey, I didn’t plagiarize and I am the one suffering. That question wouldn’t get more than 200-300 submission that got 1000.

Maybe i am wrong. I got the wrong idea about competitive programming. I should plagiarize too.

Codeforces is only better option now. Maybe because all Indians are here on codechef

Good Night.

p.s. @admin if you are reading this, please do something about this. Codechef is on a downfall and it would take much time before it loses all its value.

Bro

Follow the link , don’t report publically … i am quoting a line para from referred article .
" But despite this instruction, if you do feel that you need to say something publicly, you can use this topic. Any other new topic that you start related to this will be closed, and you will also risk getting suspended "
In short delete this post and post it under aforementioned link .

tejaswarambhe · August 22, 2021, 7:41pm

Sad to see, you should definitely mail these submissions on the plag email plagiarism@codechef.com at least their graph will get a plag symbol which will be a shame as they won’t be able to share their profile anywhere.

roastedcoderr · August 22, 2021, 8:00pm

They won’t do any thing, they haven’t since I am practicing. There are lot more better sites eg. Codeforces, Leetcode etc. where you can participate. That’s why I rarely participate here.
Also Div 2 contests are rare too.

tejaswarambhe · August 22, 2021, 8:02pm

Yeah, I prefer codeforces.

roastedcoderr · August 22, 2021, 8:09pm

There are tons of those submissions… you can not mail all those rather it should be implemented in the system.

vjvivek3 · August 29, 2021, 3:33am

CROSBLK
Submissions that I could find were plagiarized, just by looking at very few submissions.

Too much cheating in CodeChef Starters 10 Division 2 (Rated)
This is too much… These are only just few examples… There are many more
Also, Most of the solutions of CRDFLP (Div 2) are copied.

I just checked again and I can confirm A LOT of the solutions for CRDFLP (div2) are copied.
No wonder how successful submissions doubled in the last 20 mins of the contest.

It will be very easy to spot cheaters because all the cheaters have gathered on this problem. Please take action against these people.

sosa · August 29, 2021, 2:37pm

why did u delete it… Let everyone know about these people
