Look here:

int MOD=1000000007;
int MOD2=998244353;


Now look here:

void M998()
{
swap(MOD,MOD2);
}


Now look here:

Now look here:

I've answered "YES!", but you should learn that he is wrong; the only evil thing here is the function void M998().

It's so stupid and I hope coordinators won't allow such stupid things to happen (@BanRussiaAtIOI).And there's nothing wrong with his function. He wanted to use one modulo and then switch to the other. That's ugly but fine.

•  » » » » » 3 years ago, # ^ | ← Rev. 2 →   +97 No. The fact that you are childish enough to try to ruin your "career" in problemsetting and managing serious events because you love to "troll stupid schoolboys" is quite tragic though. For you, at least.

•  » » » 3 years ago, # ^ |   -27 You are stupid to create such contests. You dont deserve to be a problem setter. His rating was higher than you though. You are unfit for anything

•  » » 3 years ago, # ^ |   +176 I apologize for it. Unfortunately, I didn't notice the difference either. "Trolling" is not what we want people to expect from Codeforces rounds. I condemn using such "technics" in any rounds. They don't help people to improve themselves; they just can make people angry. We will try our best to avoid such "trolling" in the future.

•  » » 3 years ago, # ^ |   +19 That problem can be solved using FFT/NTT so wanting to disallow NTT solutions is a legit reason for it.

•  » » » » 3 years ago, # ^ |   +10 I agree. The problem had 1e9+7 before too, I wouldn't recommend this change.Having said that, I've lost a solution because of 1e9+9 instead of 1e9+7 and in problems where the output contains a typo too. Look at the bright side, this will teach people to pay attention to these details.

 » 3 years ago, # |   0 Maybe it is evil and stupid to troll other people. But by the way, it is our fault not to read the question carefully enough, or taking for granted something usual is gonna happen, or not taking simple yet precautious action to prevent ourselves from "tragedy".
