Factorial using recursion is a mathematical function that calculates the product of all positive integers up to a given number.
Define a function that takes an integer parameter n
Base case: if n is 0, return 1
Recursive case: return n multiplied by the factorial of n-1
Example: factorial(5) = 5 * factorial(4) = 5 * 4 * factorial(3) = 5 * 4 * 3 * factorial(2) = 5 * 4 * 3 * 2 * factorial(1) = 5 * 4 * 3 * 2 * 1 = 120
