Getting a descending range sequence in Ruby
range, ruby
Solution
Try this:
5.downto(1).to_a # => [5, 4, 3, 2, 1]
Of course, there's a corresponding `#upto`. If you want steps, you can do this:
1.step(10, 2).to_a # => [1, 3, 5, 7, 9]
10.step(1, -2).to_a # => [10, 8, 6, 4, 2]
Problem
So this works ascendingly ``` (1..5).to_a => [1, 2, 3, 4, 5] ``` But this doesn't ``` (5..1).to_a => [] ``` I'm trying to get a descending sequence from an arbitrary ceiling. Thanks.
