This is an editorial on Dynamic programming with Bitmasks, using the codechef problem of SEAKAM. We break the problem down to simpler parts till we can use DP.

Use Bitmasks when you can represent the state of a state in the DP using bits. Like a set of elements.

This helps keep the representation concise, and allows us to perform operations like intersection and union equivalent binary operations like AND and OR.

Thanks to Sumit Kushwara for the suggestion!
