std::ranges::elements_view<V,N>::end

constexpr auto end() requires (!__SimpleView<V> && !ranges::common_range<V>);	(1)	(since C++20)
constexpr auto end() requires (!__SimpleView<V> && ranges::common_range<V>);	(2)	(since C++20)
constexpr auto end() const requires ranges::range<const V>;	(3)	(since C++20)
constexpr auto end() const requires ranges::common_range<const V>;	(4)	(since C++20)

Returns a sentinel or an iterator representing the end of the elements_view.

Let base_ be the underlying view:

1) Equivalent to return /*sentinel*/<false>{ranges::end(base_)};.

2) Equivalent to return /*iterator*/<false>{ranges::end(base_)};.

3) Equivalent to return /*sentinel*/<true>{ranges::end(base_)};.

4) Equivalent to return /*iterator*/<true>{ranges::end(base_)};.

(none).

1,3) sentinel which compares equal to the end iterator

2,4) iterator to the element following the last element

end() returns an iterator if and only if the underlying view is a common_range: elements_view<V,F> models common_range whenever V does.

begin (C++20)	returns an iterator to the beginning (public member function)
ranges::end (C++20)	returns a sentinel indicating the end of a range (customization point object)
