Returns an iterator or a std::default_sentinel that compares equal to the end iterator of the chunk_view .

1) Available only if V models input_range . Equivalent to: return std:: default_sentinel .
2,3) Available if V models forward_range . Let base_ denote the underlying adapted view, n_ denote the stored chunk size, and iterator denote the nested iterator class.
2) Equivalent to: 
if constexpr (ranges::common_range<V> && ranges::sized_range<V>)
{
    auto missing = (n_ - ranges::distance(base_) % n_) % n_;
    return iterator<false>(this, ranges::end(base_), missing);
}
else if constexpr (ranges::common_range<V> && !ranges::bidirectional_range<V>)
    return iterator<false>(this, ranges::end(base_));
else
    return std::default_sentinel;
3) Equivalent to: 
if constexpr (ranges::common_range<const V> && ranges::sized_range<const V>)
{
    auto missing = (n_ - ranges::distance(base_) % n_) % n_;
    return iterator<true>(this, ranges::end(base_), missing);
}
else if constexpr (ranges::common_range<const V> && !ranges::bidirectional_range<const V>)
    return iterator<true>(this, ranges::end(base_));
else
    return std::default_sentinel;

Parameters
