(2) (since C++23)

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

Let current_ denote the underlying array of iterators in x , and end_ denote the underlying sentinel in y .

1) Equivalent to: return x. current_ . back ( ) - y. end_ ;
2) Equivalent to: return y. end_ - x. current_ . back ( ) ;

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

Parameters

x - an iterator
y - a sentinel

Return value

The distance between x and y .
