Write a program that lets a user enter N and that outputs N! (N factorial, meaning N*(N-1)*(N-2)*...*2*1). Hint: Initialize a variable total to N (where N is input), and use a loop variable i that counts from total-1 down to 1. Compare your output with some of these answers: 1:1, 2:2, 3:6, 4:24, 5:120, 8:40320.

Given sample code:
total = int(input()) # Read user-entered number
while i ? ??:#
Multiply total * (i-1)
# Decrement i
