template< class Iter > reverse_iterator<Iter> operator+( typename reverse_iterator<Iter>::difference_type n, const reverse_iterator<Iter>& it );		(until C++17)
template< class Iter > constexpr reverse_iterator<Iter> operator+( typename reverse_iterator<Iter>::difference_type n, const reverse_iterator<Iter>& it );		(since C++17)

Returns the iterator it incremented by n.

Parameters

n	-	the number of positions to increment the iterator
it	-	the iterator adaptor to increment

Return value

The incremented iterator, that is reverse_iterator<Iter>(x.current - n)
