How to iterate through an array starting from the last element? (Ruby)

I am trying to iterate over a list in reverse, but I have not been able to figure it out.

Here is my code:

#!/usr/bin/ruby
presidents = ["Ford", "Carter", "Reagan", "Bush1", "Clinton", "Bush2"]

for ss in -presidents.length...0
    print  ": ", presidents[ss], "\n";
end

Answer 1

use reverse_each

presidents = ["Ford", "Carter", "Reagan", "Bush1", "Clinton", "Bush2"]
presidents.reverse_each { |president| p president }
