Detailed Description
These algorithms are common
set operations performed on sequences that are already sorted. The number of comparisons will be linear.

| | [inline] |
Determines whether all elements of a sequence exists in a range using comparison.
- Parameters:
-
| first1 | Start of search range. |
| last1 | End of search range. |
| first2 | Start of sequence |
| last2 | End of sequence. |
| comp | Comparison function to use. |
- Returns:
- True if each element in [first2,last2) is contained in order within [first1,last1) according to comp. False otherwise.
This operation expects both [first1,last1) and [first2,last2) to be sorted. Searches for the presence of each element in [first2,last2) within [first1,last1), using comp to decide. The iterators over each range only move forward, so this is a linear algorithm. If an element in [first2,last2) is not found before the search
iterator reaches
last2, false is returned.

Determines whether all elements of a sequence exists in a range.
- Parameters:
-
| first1 | Start of search range. |
| last1 | End of search range. |
| first2 | Start of sequence |
| last2 | End of sequence. |
- Returns:

This operation expects both [first1,last1) and [first2,last2) to be sorted. Searches for the presence of each element in [first2,last2) within [first1,last1). The iterators over each range only move forward, so this is a linear algorithm. If an element in [first2,last2) is not found before the search

Return the difference of two sorted ranges using comparison functor.
- Parameters:
-
| first1 | Start of first range. |
| last1 | End of first range. |
| first2 | Start of second range. |
| last2 | End of second range. |
| comp | The comparison functor. |
- Returns:
- End of the output range.
This operation iterates over both ranges, copying elements present in the first range but not the second in order to the output range. Iterators increment for each range. When the current element of the first range is
less than the second according to
comp, that element is copied and the
iterator advances. If the current element of the second range is
less, no element is copied and the
iterator advances. If an element is contained in both ranges according to
comp, no elements are copied and both ranges advance. The output range may not overlap either input range.

This operation iterates over both ranges, copying elements present in the first range but not the second in order to the output range. Iterators increment for each range. When the current element of the first range is
less than the second, that element is copied and the
iterator advances. If the current element of the second range is
less, the
iterator advances, but no element is copied. If an element is contained in both ranges, no elements are copied and both ranges advance. The output range may not overlap either input range.

This operation iterates over both ranges, copying elements present in both ranges in order to the output range. Iterators increment for each range. When the current element of one range is
less than the other according to
comp, that
iterator advances. If an element is contained in both ranges according to
comp, the element from the first range is copied and both ranges advance. The output range may not overlap either input range.
