Task

If you can't sleep, just count sheep!!

Task: Given a number, 3 for example, return a string with a murmur: "1 sheep...2 sheep...3 sheep..."

Note: You will always receive a positive integer.

Solution

def count_sheep(num)
  (1..num).map {|i| "#{i} sheep..."}.join
end

Explanation

The code returns from 1 to the designated number but iterates each time by interpolating the number to "sheep..." which is returned in an array and finally joined together to make it one long string.

This was difficult to describe, perhaps I don't know it well enough...
