Hello, what's up ?!

I prepared another problem, but this time, some part of the problem is similar to one on codechef, which I of course came to know later. Anyways : try this -> https://mirror.codeforces.com/contestInvitation/bbf072a86e816262a0c0bb3ed00f595c168d0276.

I hope you will find the problem new! XD

Edit: Solution code : https://ideone.com/hhbkjX

Neat, had to think about this for a good bit. Curious as to what the "official" solution/proof is since mine was rather Guessforces lmao
