title: How to specify number of inputs and get these inputs in Ruby?
body: <p>I'm new to ruby, I'm trying to create a program that asks the user for number of elements, then input those elements, and then bubbles sort them. </p>
  
  <pre><code>  class BubbleSort
      def sort(to_sort)
        # move the array to sort into a variable, which will be used for recursion
        arr_to_sort = to_sort
        # assume that we haven't swapped any values yet
        swapped = false
        # lower the length by one because we can't compare the last value since it's at the end
        length_of_sort = arr_to_sort.length - 1
        # begin loop through each value
        length_of_sort.times.each do |i|
          # if the value we're on is greater than the value to the left of it, swap
          if arr_to_sort[i] &gt; arr_to_sort[i+1]
            # store values to be swapped
            a, b = arr_to_sort[i], arr_to_sort[i+1]
            # remove value we're on
            arr_to_sort.delete_at(i)
            # insert the value to the right, moving the lesser value to the left
            arr_to_sort.insert(i+1, a)
            # swap is true since we did a swap during this pass
            swapped = true
          end
        end
        if swapped == false
          # no swaps, return sorted array
          return arr_to_sort
        else
          # swaps were true, pass array to sort method
          bubble_sort = BubbleSort.new
          bubble_sort.sort(arr_to_sort)
        end
      end
    end

  <p>I tried to get inputs from the user, but it doesn't work. Can someone help me out on how to make the user specifies the number of elements and then get these inputs?    </p>
