Hello,

My program continually TLEs on test case 10 (https://codeforces.me/contest/1344/submission/79225885) and I have no clue why. My code has passed larger cases quickly and I've yet to find bugs leading to infinite loops.

Any help would be greatly appreciated

Why is this group filled with alternate accounts at master rating? https://codeforces.me/ratings/organization/8059

Does anyone understand why all the problems are marked with 2-SAT?

I thought this was a relatively advanced topic (especially for someone like me :P), and yet some Div2 C & D problems are being marked with this tag.
