WebSo the bitmask 01010 represents the subset {2,4}. Now the benefit of using bitmask. We can set the ith bit, unset the ith bit, check if ith bit is set in just one step each. Let's say the bitmask, b = 01010. Set the ith bit: b (1< WebErrichto's blog. Bitwise operations 2 — popcount & bitsets. Part 1 ( link) introduces basic bitwise operations. This is part 2 and it's mainly about (in)famous bitsets and example problems. Also, see links to very useful advanced stuff at the bottom.

"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.
