COCI 2016 Vjestica
- Firstly, notice that N is very small. This implies that we should use a bitmask
- For each mask, we split the active words into 2 groups and solve recursively for those
- solve(mask) = min(solve(A) + solve(B)) where A + B = mask, A & mask == A, B & mask == B, and A & B == 0
- Complexity: O(N log N * 2^N)
