Hi to all,
I have learned dp and bitmask but i want to mix between them.
I want a simple tutorial about dp with bitmask and a simple problem explain the basic idea and it would be useful if you provide me with DP with bitmask problems sorted by difficulty .
Hope to help me , thanks in advanced .
Finally i got the idea behind using bitmask with Dp as rng_57 said it's just used as state.
