## set_difference

Syntax:

        #include <algorithm>
        template< typename InIterA, typename InIterB, typename OutIter >
        OutIter set_difference( InIterA start1, InIterA end1, InIterB start2, InIterB end2, OutIter result );
        template< typename InIterA, typename InIterB, typename OutIter, typename StrictWeakOrdering >
        OutIter set_difference( InIterA start1, InIterA end1, InIterB start2, InIterB end2, OutIter result, StrictWeakOrdering cmp );

The set_difference() algorithm computes the difference between two sets defined by [start1,end1) and [start2,end2) and stores the difference starting at result.

Both of the sets, given as ranges, must be sorted in ascending order.

The return value of set_difference() is an iterator to the end of the result range.

If the strict weak ordering comparison function object cmp is not specified, set_difference() will use the < operator to compare elements.
