set_intersection
この関数は2つの集合オブジェクトを受け取り、それらの共通部分を求めます。
#include <dlib / set_utils.h>
template <
typename T,
typename U,
typename V
>
void set_intersection (
const T& a,
const U& b,
V& i
);
/*!
requires
- T, U, and V must all be implementations of set/set_kernel_abstract.h
- the types of objects contained in these sets must be copyable
ensures
- #i == the intersection of a and b. That is, i contains all elements
of a that are also in b.
