set_union
Syntax: #include <algorithm> iterator set_union( iterator start1, iterator end1, iterator start2, iterator end2, iterator result ); iterator set_union( iterator start1, iterator end1, iterator start2, iterator end2, iterator result, StrictWeakOrdering cmp ); The set_union() algorithm computes the union of the two ranges [start1,end1) and [start2,end2) and stores it starting at result. The return value of set_union() is an iterator to the end of the union range. set_union() runs in linear time. Related topics:
