This project demonstrates how recursion works in Python by calculating the factorial of a number. It is designed as a beginner-friendly project that helps understand recursive functions, base cases, and user input handling.
Recursion is a programming technique in which a function calls itself to solve a problem.
Every recursive function contains:
- Base Case
- Recursive Case
Without a base case, recursion will continue indefinitely and eventually cause an error.
The factorial of a non-negative integer is the product of all positive integers less than or equal to that number.
Example:
5! = 5 × 4 × 3 × 2 × 1 = 120
Special Cases:
0! = 1
1! = 1
n! = n × (n−1)!
Base Case
0! = 1
- Recursive implementation
- User input support
- Input validation
- Well-documented code
- Beginner-friendly
- Modular design
