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 enumerate_view::sentinel

x	-	an iterator
y	-	a sentinel

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

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