Hello everyone,

I was solving the last problem from the last CF Round! http://mirror.codeforces.com/contest/676/problem/E

I can't understand why at the end of the game if P(k) = 0 then the human wins, I mean why if P(k) = 0 then it means that the polynomial P(x) is divisible by polynomial Q(x)?

I really need your help! :)
