Bitmask dp codeforces

WebInteresting! I have independently reconstructed the Aho-Corasick DFA in the past but did not know its name. My solution to problem F is superficially very different, using a bitmask-DP, but I expect that the reachable bitmasks are nearly in one-to-one correspondence with the states of the Aho-Corasick DFA.

WebWhat we would like to do is to deduce that y = 0 modn from the fact that 2y = 0 modn. However, remember that n is even so n = 2m for some m in Z. Taking y = m, 2y = 0 modn but y ≠ 0 modn. Therefore, you cannot assume that x + f(f + 1) 2 = 0 modn if you only know that 2x + f(f + 1) = 0 modn.
