(2)

(since C++23)

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

1) Equivalent to: return x.inner_ - y.inner_;.

2) Equivalent to: return y.inner_ - x.inner_;.

These function templates are not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when adjacent_transform_view::sentinel is an associated class of the arguments.

Parameters

x	-	the iterator
y	-	the sentinel

Return value

The distance between iterator and sentinel.
