Understanding and Implementing Bubble Sort in Ruby

You’ll probably never need to implement bubble sort from scratch. Just call Array#sort! But sorting algorithms are a popular interview topic for a reason. They ask a bigger question: “Sure, you know what your code does, but do you know how it works?
