Similarly all of the above are also cheated in other 2 questions of this contest please check those questions also.

I kindly request to codechef that please go through these users ids and take strict action against them.

Please go through the solutions of Non Coprime Neighbours of today’s starter.
nearly 75% of the codes in DIV 2 are similar to this code I found in a link uploaded - Non Comprime Neighbour solution - Google Drive by this YouTube channel - - YouTube and the only difference is in how he loop might be initialized or in the spacing or changed names of the variable but rest everything remains the same. I get that this is a way to solve it and a lot of people would have had this idea but it is easily identifiable when someone is clearly trying to change the solution and some don’t even bother to do that too the submission for this question spiked as soon as solution came out.

I request you and anyone else to go through them once most of them are in C++ as the language of the solution was in C++ too some could have done the same in a different language. Thankyou

CodeChef: Practical coding for everyone this too

Over 300 people submitted successfully for problem 4 in Codechef Starters 29 (div2) in the last 10 minutes. This happens every time in every contest, are CodeChef doing something about it?
These type of instances deeply demotivates people who are trying hard to improve their ratings.

Hey @admin look at these two solution https://www.codechef.com/viewsolution/61177978 and https://www.codechef.com/viewsolution/61169862
from codechef starter 31, looks exactly same to me. They just changed the variable. The guy @lucif_3r 's one of the account was banned due to continuous plaig in multiple contest yet he is cheating again. Have a look at these submissions.

man woke up and choose violence​:rofl::rofl::rofl:

So basically this entire college is cheating. Totally another level of thing.

This was the first time only so please don’t take it that way and also they all have been plaigirised for the same. Also i am deleting the post because the purpose of reporting and getting plaigirised is served. just to avoid any hatred.
