Luna::set_intersection
template <typename _InputIt1, typename _InputIt2, typename _OutputIt>
_OutputIt set_intersection(_InputIt1 first1, _InputIt1 last1, _InputIt2 first2, _InputIt2 last2, _OutputIt d_first)
Constructs a sorted range consisting of elements that are found in both sorted ranges.
Parameters
-
in first1
The iterator to the first element of the first range.
-
in last1
The iterator to the one-past-last element of the first range.
-
in first2
The iterator to the first element of the second range.
-
in last2
The iterator to the one-past-last element of the second range.
-
in d_first
The iterator to the first element of the destination range.
Return value
Returns one iterator to the one-past-last element of the destination range.
Remark
If [first1
, last1
) contains m
elements that are equivalent to each otherand [first2
, last2
) contains n
elements that are equivalent to them, the first min(m, n)
elements will be copied from [first1
, last1
) to the output range, preserving order.
Valid Usage
- Elements in the ranges specified by [
first1
,last1
) and [first2
,last2
) must be sorted in non-descending order.
