#016StarterLoopsNumbers3 min

n people can line up in 1 × 2 × 3 × … × n different orders. Write line_ups(n) to multiply it out with a loop. For n of 0, return 1.

Examples

line_ups(3)→6

line_ups(5)→120

main.py

def line_ups(n):
    ways = 1
    for i in range(1, n + 1):
        # your code here: multiply ways by i
        pass
    return ways
