Question

I need some help with the following:

1. in a method create a new array based on the input parameter
2. return an array from that method
3. output the contents of the array the most elegantly?

mycontroller.rb

def test(num)
  #take the number and create a new array and return the array with the numbers.
  #example input: 5
  #output: array with 5 indexes and values of [1,2,3,4,5]
end

# output the contents of the array
i = 0
while i < 5
  puts test(i)
end

Thanks!

You can use ruby ranges for this:

list = (1..num).to_a

To print an array use the inspect method, i.e.

puts list.inspect
