WebApr 9, 2024 · Bitmask DP is a type of dynamic programming that uses bitmasks, in order to keep track of our current state in a problem. A bitmask is nothing more than a number that defines which bits are on and off, or a binary string representation of the number.

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.
