# The factorial function says to multiply all whole numbers from our

# number down to 1.

#

# Examples: 4! = 4 × 3 × 2 × 1 = 24.

def factorial(n):

result = 1 # Initialize the result variable outside the loop

while n > 1: # Use a condition to control the loop

result *= n # Update the result variable by multiplying with the current value of n

n -= 1 # Decrement n to move towards the base case

return result # Return the final result after the loop

# Test Cases

print(factorial(5))

print(factorial(0))
