Overview

Stack is a linear data structure in which elements are added and removed from one end only, called TOP. It follows the LIFO principle, meaning the last element inserted is the first one removed. Python implements a stack conveniently using the list data type with append() and pop(). Stack is useful

Key Concepts

A stack is a linear data

A stack is a linear data structure in which insertion and deletion happen from one end only, called TOP. The most recent element is removed first.

LIFO means Last

LIFO means Last-In-First-Out. The element inserted last is the first one to be removed.

TOP is the end from

TOP is the end from which elements are added or deleted. In Python list-based implementation, this is the rightmost end.

PUSH is the insertion operation on

PUSH is the insertion operation on a stack, and POP is the deletion operation. PUSH adds an element at TOP, while POP removes the topmost element.

Overflow occurs when an element

Overflow occurs when an element is added to a full stack. Underflow occurs when an element is removed from an empty stack.

Learning Objectives

  • Define stack as a linear data structure and identify the TOP
  • Explain the LIFO principle clearly
  • Describe PUSH and POP operations and their exceptions
  • Understand stack implementation in Python using list, append(), and pop()
  • Use stack-related functions such as isEmpty, size, top, opPush, opPop, and display
