    operator- ( const /*sentinel*/ & y, const /*iterator*/ <OtherConst> & x ) ;
(2) (since C++23)

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 zip_transform_view::sentinel

Parameters

x - an iterator
y - a sentinel

Return value

Let inner_ denote the underlying iterator or sentinel respectively.

1) x.inner_ - y.inner_
2) y.inner_ - x.inner_
