Recursion Example - Factorial of a Number

This video tutorial introduces the concept of recursion using the factorial function as a common example. It explains how to calculate the factorial of a number, discusses the importance of the base case in recursion, and derives the pattern and formula for factorial calculation. The tutorial then demonstrates how to implement a recursive factorial function in Python, followed by executing and testing the function to ensure it works correctly. The video aims to enhance understanding of recursion and its application in programming.
