I don’t know any cheaters
I want to report a user on CodeChef who copied solutions from YouTube videos during the Starters 118 Division 4.
He has copied this solution:CodeChef: Practical coding for everyone completely 100% from this YouTube video: https://www.youtube.com/watch?v=qbXMINfMU4o

He has copied this solution: CodeChef: Practical coding for everyone completely 100% from this YouTube video: https://www.youtube.com/watch?v=WJgosI3YWTE
His solution: CodeChef: Practical coding for everyone is not 100% copied but very similar to the solution shown in the YouTube video: https://www.youtube.com/watch?v=KFMc9x5OXNY
All of these videos were published while the contest was going on CodeChef, that is around 9 PM IST. He also changed his coding language from C++ to Python during the contest which is also suspicious.

Apart from the above mentioned YouTube channel, the solution: CodeChef: Practical coding for everyone also matches 100% with the solution circulated on the telegram group: HERE, during the contest.

I’m attaching the screenshots below.
There is a fair chance that the user is using Telegram and YouTube channels to copy solutions.
Even this code of another User: CodeChef: Practical coding for everyone, 100% matches the code: CodeChef: Practical coding for everyone of the above mentioned User copied from Telegram and YT channels during the contest as described above in detail.
Same goes for this solution: CodeChef: Practical coding for everyone by User, he has just changed the variable names.

an advice to codechef deploy a checker atleast for avoiding palagrim we could see that exactly same solutions are also passing the checker even the variable names are not been changed. i am sorry but it doesn’t give a good feeling as a contest giver but anyways if cheating happens or not i dont care i am here to increse my problem solving skills and rating are just a bonus for me personally…
but you can use accuracy for that checking even as if a question accuracy percentage is stagnant for around 5 percent for whole contest but in the end it 10 min or the time it start to increseing abruptly there might be chances that solution is available to the public . suppose it reached to 20 percent then there might be something fishy going on…
These are the contestants with same solution for this problem in div-2.
We can clearly understand that these contestants have cheated.
Here are are some of the solutions:

They think we are stupid.

One would say that a 3* don’t need to cheat, but holy!
I mean, they don’t know that a syntax tree will detect similarities despite the name of the variables??
The code is absolutely redundant lol
