Computes the distance between the underlying iterator of x and the underlying sentinel of y.
Let last_ele_ denote the underlying iterator of x and end_ denote the underlying sentinel of y.
1) Equivalent to: return x.last_ele_ - y.end_;.
2) Equivalent to: return y.end_ - x.last_ele_;.
These functions are not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when slide_view::sentinel is an associated class of the arguments.
Parameters
| x | - | an iterator | 
| y | - | a sentinel | 
Return value
The distance between the iterator and the sentinel.
