Chapter Overview
This chapter introduces the concept of a stack—a linear data structure that follows the Last-In-First-Out (LIFO) principle. It covers fundamental operations like push and pop, stack implementation using Python lists, checking overflow and underflow conditions, and real-world applications such as function call management, undo operations, and expression parsing.
