Doing a VContest and this fucking question in a bar that's open for some reason in the afternoon (I'm the only one here lol), and this fucking problem, sooooo fucking annoying. LITERALLY MAKES ME WANT TO PUNCH SOMEONE!!!!!!!!!!!!

Gonna go for a walk then solve it today, no matter what. SO fucking annoying that I can't solve hard codeforces problems.
