Defined in header <experimental/ranges/algorithm>
template< RandomAccessIterator I, Sentinel<I> S,           class Comp = ranges::less<>, class Proj = ranges::identity >     requires Sortable<I, Comp, Proj> I sort( I first, S last, Comp comp = Comp{}, Proj proj = Proj{} );	(1)	(ranges TS)
template< RandomAccessRange R,           class Comp = ranges::less<>, class Proj = ranges::identity >     requires Sortable<ranges::iterator_t<R>, Comp, Proj> ranges::safe_iterator_t<R> sort( R&& r, Comp comp = Comp{}, Proj proj = Proj{} );	(2)	(ranges TS)

1) Sorts the elements in the range [first, last) in ascending order. The order of equal elements is not guaranteed to be preserved. Elements are compared using comp after applying the projection proj.

2) Sorts the elements in the range r, as if by return ranges::sort(ranges::begin(r), ranges::end(r), comp, proj);.

Notwithstanding the declarations depicted above, the actual number and order of template parameters for algorithm declarations is unspecified. Thus, if explicit template arguments are used when calling an algorithm, the program is probably non-portable.

Parameters

first, last	-	the range of elements to sort
r	-	the range of elements to sort
comp	-	the comparator to use
proj	-	the projection to apply to elements in the range

Return value

An iterator pointing past the end of the range (i.e., it compares equal to last for overload (1), and ranges::end(r) for overload (2)).

Complexity

O(N·log(N)) comparisons, where N is equal to the number of elements in the range.
