Return Value Solutions

#2. Write a method called #times_three_and_plus_five that accepts an integer, n, as an argument. Your method should multiply n by 3, and then add 5. For example, times_three_and_plus_five(4) should return 17. Do this using an explicit return.

  def times_three_and_plus_five(n)
    return (n * 3) + 5
  end

#3. Change your #times_three_and_plus_five method to instead use an implicit return.

  def times_three_and_plus_five(n)
    (n * 3) + 5
  end

#5. Write a method called #even_or_odd, that accepts an integer as an argument. Your method should return the string "even" if the integer is even, and return "odd" if the integer is odd. Follow the pattern used in the #is_billy? method from the reading. Also, use the #even? and #odd? methods we explored in the previous step.

  def even_or_odd(n)
    if n.even?
      return "even"
    end
    "odd"
  end
