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.
