Welcome to the algorithm section of this course. The next few sections will surely be interesting as we are going to talk about some advanced topics in computer science. These algorithms will help you understand how programming works and give you the tools you'll need to build your own advanced programs.

We'll start out with the sorting algorithms. The reason why we're starting with sorting is because it supplies some of the foundational knowledge that you'll be able to use in more advanced topics, as you'll see as you work through the section.

To explore sorting, let's start by creating an array:
