Codewars Challenge 2 - Count by X

count_by_x.rb

#Create a function with two arguments that will return a list of length (n) with multiples of (x).
#Assume both the given number and the number of times to count will be positive numbers greater than 0.
#Return the results as an array (or list in Python, Haskell or Elixir).
#Examples:
#count_by(1,10) should return [1,2,3,4,5,6,7,8,9,10]
#count_by(2,5) should return [2,4,6,8,10]

#My Solution:

def count_by(x, n)
  (1..n).map { |item| item * x }
end
