I think the most difficult problem in this contest is at most *2200 :(

so it like div.3.

Is it Div.3?

Thanks for this rubbish trash boring disgusting fucking meaningless Problem C that I didn't have enough time to write E

+14

How to reach master?

why? I guessed one so I get accepted during the contest.

A problem that you can solve it only by guessing a simple conclusion.

Sorry for my rudeness , I think ConclusionForces is boring, Problem ABCEF is all Conclusion problems.
