Chapter 3.  Stacks

You learned in the previous chapter how to create and use arrays, which are the most common type of data structure in Computer Science. As you learned, we can add and remove elements from an array at any index desired. However, sometimes we need some form of data structure where we have more control over adding and removing items.
