@shaily_adm
A common similarity between most of the codes was mention of some TIH, and the others are replicated versions of the same with slight modifications for obvious reasons.

These students have cheated in the Codechef starters contest 28. They have same solution, just changes the variables. Please look into the matter.

Similarly, these users have similar solution

It will be helpful, if you can tell us about the status of report.

Thanks

Nothing will happen bro , Codechef plagiarism checker is good for nothing . If you are honest , you will suffer , it is the harsh reality.

@shaily_adm when can we get the stats for starters 26,27,28,29 Feb-cookoff and Feb lunchtime at least. Its been over a month and cheaters who have been plagiarised are still cheating. Please take some action. Please inform us about the relevant stats as we were told we will know the relevant stats in 10 days but its been over a month

cheat_reporter · March 17, 2022, 10:24am

Rampant cheating in Stater 30.
Problem: MLIS

Code difference of first and last Python submission

CodeChef: Practical coding for everyone submitted at 21:26:45
CodeChef: Practical coding for everyone submitted at 22:59:35

Almost all PYTH 3.6 and PYPY 3 submissions have the same code with little to no changes.
AC Submissions PYTH 3.6
AC Submissions PYPY3

Combining them, 450+ submissions are based on the same code.

@admin

hello12x · March 17, 2022, 1:24pm

@cheat_reporter @admin @shaily_adm seeing the pattern many submissions are different and many are common too. Even if the logic was not that difficult and it could have been done in this way by many. So definitely all 450 submissions are not having the same submissions but around 30 percent are the same. I checked almost 60+ have the same code and the CodeChef team is not giving us any statistics about plagiarism in the past contests sadly
