python

def factorial(n):
pass # replace this line with your lines of recursive code
def sum_recursively(n):
pass # replace this line with your lines of recursive code
def sumlist_recursively(l):
pass # replace this line with your lines of recursive code
def reverse_recursively(l):
pass # replace this line with your lines of recursive code
#EXTRA CREDIT
def multiply_recursively(n, m):
pass # replace this line with your lines of recursive code

1. Factorial
In math, if you have a number n, the factorial function (written n!) computes
nx (n-1) x (n-2) x (n-3) x ... x1. For example:
• 0! is defined to be 1
• 1! =1
• 2! = 2 x1=2
• 3! = 3 x 2 x1 = 6
• 4! = 4x 3 x 2x1= 24
• 5! = 5 x 4x 3 x 2 x1= 120
Add your code to the provided function signature so it computes the factorial of the
integer it is given. You may not use math.factorial( in your function.
