We learned in the previous chapter how to create and use arrays, which are the most common type of data structure in computer science. As we 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. There are two data structures that have some similarities to arrays, but which give us more control over the addition and removal of elements. These data structures are stacks and queues.

In this chapter, we will cover the following topics:

  • The stack data structure
  • Adding elements to a stack
  • Popping elements from a stack
  • How to use the Stack class
  • Different problems...
