Let current_ denote the underlying tuple-like object of iterators to elements of adapted views.

1,2) Returns the iterator i incremented by n. Equivalent to: auto r = i; r + = n; return r;
3) Returns the iterator i decremented by n. Equivalent to: auto r = i; r - = n; return r;
4) Let DIST(k) be difference_type(std:: get <k> (i.current_ ) - std:: get <k> (j.current_ ) ) . Returns the smallest absolute value among DIST(n) for all integers 0 <= n < sizeof...(Views)

These functions are not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when zip_view::iterator<Const>

Parameters

i, j - the iterators.
n - position relative to current location.

Return value

1,2) a copy of i that is advanced by n
3) a copy of i that is advanced by -n
4) the distance between i and j
