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

| ) |
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
- True if each element in [first2,last2) is contained in order within [first1,last1). 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). 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 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.

| ) |
Return the difference of two sorted ranges.
- Parameters
-
first1 Start of first range. last1 End of first range. first2 Start of second range. last2 End of second range.
- 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, 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.

Return the intersection of two sorted ranges.
- Parameters
-
first1 Start of first range. last1 End of first range. first2 Start of second range. last2 End of second range.
- Returns
- End of the output 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, that iterator advances. If an element is contained in both ranges, the element from the first range is copied and both ranges advance. The output range may not overlap either input range.

Return the symmetric difference of two sorted ranges.
- Parameters
-
first1 Start of first range. last1 End of first range. first2 Start of second range. last2 End of second range.
- Returns
- End of the output range.
This operation iterates over both ranges, copying elements present in one range but not the other in order to the output range. Iterators increment for each range. When the current element of one range is less than the other, that element is copied and the iterator advances. 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.
