incremental array in ruby, 0..40, [10, 20, 30, 40]

Question

How can I offset this array so it only outputs every ten numbers?

(0...40)
[10,20,30,40]

Answer 1

Use the step method for this:

10.step(40,10)

The first argument is the number you want to count up to, with the second argument being the "steps" that you take to get there.
