Recursion in Python: Factorial with Debugging...

What is Recursion? Recursion is a technique where a function calls itself to solve a problem step by step. Instead of using loops, recursion breaks a problem into smaller subproblems. Factorial Using Recursion Factorial of a number means: 5! = 5 × 4 × 3 × 2 × 1 = 120 Python Code def factorial(n): if n == 1: return 1 return n * factorial(n - 1) print(factorial(5)) Debugging the Code (Step-by-Step Execution) Let’s trace what happens when we call: factorial(5) Function Calls factorial(5) = 5 * fact
