🔄 Factorial Using Recursion in C# Explained!

In this quick C# tutorial, we calculate the factorial of a number using recursion — a powerful concept where a function calls itself.

🧠 What is Recursion?
Recursion is a programming technique where a function calls itself repeatedly until a specific condition is met. It's often used to solve problems that can be broken down into smaller, similar subproblems.

✅ Factorial Definition:
The factorial of a number n (written as n!) is the product of all positive integers less than or equal to n.

📌 Example:
5! = 5 × 4 × 3 × 2 × 1 = 120
