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 is an associated class of the arguments.

Parameters

x	-	an iterator
y	-	a sentinel

Return value

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

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