Great job, man!

Here are some suggestions:

• Use 'unless' instead of 'if !'
• Try to implement the bubble_sort_by using yield, in a way that calling: array = [ 3, 5, 1, 4 ] bubble_sort_by(array) { |x, y| y - x } The result should be [ 5, 4, 3, 1 ]

Keep the great job!!

def bubble_sort(array) loop do switch = false (array.length - 1).times do |index| if array[index] > array[index += 1] array[index], array[index += 1] = array[index += 1], array[index] switch = true end end break if !switch end array end array = [8,6,2,7,3,4,9] puts bubble_sort(array)
