Range consolidation: Difference between revisions

=={{header|Raku}}==

(formerly Perl 6)

In Raku, a Range is a first class object with its own specialized notation. Raku Ranges allow for exclusion of the boundary numbers. This example doesn't since it isn't a requirement in this task. Much of the logic is lifted from the [[Set_of_real_numbers#Raku|Set_of_real_numbers]] task with simplified logic for the much simpler requirements.

-> @intervals {

say reverse consolidate |@intervals.grep(*.elems)».sort.sort({ [.[0], .[*-1]] }).map: { Range.new(.[0], .[*-1]) }
