WebI think int is easier to use for bitmask dp because it is easier to store and loop through all possible states. The main use for bitset I have seen is when you have an O(n 2) dp solution and are looking for an extra speed boost to squeeze it in the time limit. Definitely a cool trick that makes problem setters sad/apologetic when it works. WebWith Boost.Bimap you can create associative containers in which both types can be used as key.
