How to write negative loop in ruby like for(i=index; i >= 0; i --)

Question

How can I write a loop in Ruby that counts down, similar to the following C-style for loop?

for (i = 25; i >= 0; i--) { 
    print i;
}
         


        

Answer 1

downto is fine, but there is also the more generic step.

25.step(0, -1){|i| puts i}
