requires std::sized_sentinel_for < ranges::sentinel_t <Base>,
ranges::iterator_t < /*maybe-const*/ <OtherConst, V>>>
friend constexpr ranges::range_difference_t < /*maybe-const*/ <OtherConst, V>>

    operator- ( const /*sentinel*/ & y, const /*iterator*/ <OtherConst> & x ) ;
(2) (since C++20)

Computes the distance between the underlying iterator of x and the underlying sentinel of y.

These function templates are not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when elements_view::sentinel

Parameters

x - an iterator
y - a sentinel

Return value

1) x.base() - y.base()
2) y.base() - x.base()
