26.7.31 Stride view [range.stride]

26.7.31.1 Overview [range.stride.overview]

stride_view presents a view of an underlying sequence, advancing over n elements at a time, as opposed to the usual single-step succession.
The name views​::​stride denotes a range adaptor object ([range.adaptor.object]).
Given subexpressions E and N, the expression views​::​stride(E, N) is expression-equivalent to stride_view(E, N).
[Example 1: auto input = views::iota(0, 12) | views::stride(3); ranges::copy(input, ostream_iterator<int>(cout, " ")); // prints 0 3 6 9 ranges::copy(input | views::reverse, ostream_iterator<int>(cout, " ")); // prints 9 6 3 0 — end example]
