Updates on curtailing plagiarism

first 6 questions were leaked. pls look in to the matter asap @admin

In the last 20minutes submission count of K distant array went from 500 to 1700 real quick. Making a huge drop in my rating. All the solutions get leaked online and you people barely bat an eye on it.

It’s really unfair for those who tries to grind here on codechef. And might lose the interest to participate here if things keep going like this.

@admin @shaily_adm @utkarsh_adm time to plag him…

For LTIME104B , plz plag @aarindey
He has been doing cheating for a very long time .
Here are a few examples in LTIME104B
Problem :- PERMXORSUM
His solution
https://www.codechef.com/viewsolution/57365872
EXACTLY similar to these solutions,

  1. Solution: 57381945 | CodeChef
  2. Solution: 57382004 | CodeChef
  3. Solution: 57382063 | CodeChef
  4. Solution: 57382127 | CodeChef
  5. Solution: 57382410 | CodeChef
    And many more…

I didnt go further , I think 5 should be enough to proove my point .
All of them has the EXACT same code , some even have the same indentation . They have simply copied it from somewhere and pasted it here without knowing anything about the problem .

He has reached 4 stars by doing these things and then writing stupid posts on Linkedln.
@admin @shaily_adm

bro dont talk to him he is a fraud​:joy::joy: i think we both should report him

bro tune jo reply diya most savage :rofl::rofl::rofl:

Sahi hai bhai you were not guilty jbki u were caught in plagiarism while I am guilty jbki maine 300 submissions ke andar submit kiya thaa…

Iss contest mai Div 2 mai DISTK leak 500 submissions ke baad hua woh bhi last 20 minutes mai… and I submitted way before that at 9:30 PM there is no case of cheating…

You guys need to understand and have the logical ability to solve these problems before mudslinging, in a previous comment I had told POLIN could be best solved by taking two hashsets and finding the sum of their sizes… around 2k submissions were made in first 15 minutes in Div 2, I am sure most did it like that, will you call that plagiarism too… let MOSS figure out the plagiarism…

Tumhare liye MOSS ka plagiarism plagiarism nhi because you were caught in that… but khud ka banaya plagiarism standard banaye hai… :rofl:

Though these two submissions are in two different languages, each and every instructions are same.
Exact code conversion have been done.

in the recent codechef starters, there were a bunch of illegitimate solution for the D problem of Div2. This is quite obvious when you look at the number of solves in the last 5 minutes.
This is truly depressing and ruins the spirit of competition.
I’ve attached a few illegitimate solution below. admins, please take the required action.

These are some of the obvious cheaters -

8 out of the 9 solutions for DIVIDEARR problem were written in java and all of them are the same. And There is one c++ solution , i don’t’ know if the guy actually solved or just coded the logic of that java code in c++. But for sure those java 8 submissions are all by cheaters.

I hope it wont be a difficult task for you guys to plagiarize and looks into these 7 submissions and take actions against them.
