#
split_­view takes a view and a delimiter, and splits the view into subranges on the delimiter.
The delimiter can be a single element or a view of elements.
2
#
The name views​::​split denotes a range adaptor object ([range.adaptor.object]).
Given subexpressions E and F, the expression views​::​split(E, F) is expression-equivalent to split_­view{E, F}.

}
// The above prints: the*quick*brown*fox*
