Chapter 3 - Stacks

Do you want to learn more about one of the most important data structures in computer science? Do you want to understand how stacks work and how they are used in various applications? Do you want to practice and implement stacks using Python as a programming language?

If you answered yes to any of these questions, then you will find this chapter very useful. In this chapter, you will learn about the concept and implementation of stacks. Stacks are linear data structures that follow the principle of last in first out (LIFO). Stacks are used to store and retrieve data in a specific order.

Some of the topics you will cover in this chapter are:

• The definition and properties of stacks: How stacks are defined and characterized by their operations and features. 📝👩‍🏫👨‍🎓
• The implementation of stacks: How stacks are implemented using arrays or linked lists as the underlying data structures. 📊📈📉
• The applications of stacks: How stacks are used in various domains and purposes such as expression evaluation, recursion, backtracking, etc. 🔬⚒️💰
• The Python code for stacks: How stacks are coded and executed using Python as a programming language. 💻🐍👍

By studying this chapter, you will gain a deeper understanding of how stacks are essential and versatile data structures  in computer science. You will also develop critical thinking skills to solve various problems and cases using stacks. You will also appreciate the importance of Python as a simple and powerful language  for implementing stacks.
