Day 6: Factorial

DAY 6 OF 90 · Count it

Factorial

Easy90 Days of Looping

Inputs

n is a whole number from 0 to 10.

Your tasks

Create a number product that starts at 1.
Use a loop to multiply product by each whole number from 1 up to and including n.
Complete factorial so it returns product. Return it, do not print it.

Example

With n = 5, factorial returns 120.

Rules

The product of no numbers is 1, so factorial(0) is 1.

Test data

TEST DATA 1: n is 5

TEST DATA 2: n is 0

Practice focus

Loops that count, add up and multiply. Every algorithm starts here: a counter, a total and a stopping point.
