How to do intersection and union for sets of the type tr1::unordered_set in c++? I can't find much reference about it. Any reference and code will be highly appreciated. Thank you very much. Update: I just guessed the tr1::unordered_set should provide the function for intersection, union, difference.. Since that's the basic operation of sets. Of course I can write a function by myself, but I just wonder if there are built in function from tr1. Thank you very much.
