Project: Bubble Sort

• Build a method #bubble_sort that takes an array and returns a sorted array. It must use the bubble sort methodology.

Project: Bubble Sort By

• Now create a similar method called #bubble_sort_by which sorts an array but accepts a block. The block should take two arguments which represent the two elements currently being compared. Expect that the block’s return will be similar to the spaceship operator you learned about before – if the result of the block is negative, the element on the left is “smaller” than the element on the right. 0 means they are equal. A positive result means the left element is greater. Use this to sort your array.
