Question 34 Write a recursive function fac2(n) to compute the factorial of n. n!-1 23 ".. (n-1) t n ni # n * (n-1) * " 3 * 2 * 1 orn

Answer 1

def fac2(n): # function defination start
if n == 1: # last execution for value n =1. program #executes for n, n-1. n-2 and so on
return n
else:
return n*fac2(n-1)

Factnum = int(input("Enter Number of which factorial is required ")) # Accept #number whose factorial is required, convert to integer else error with phthon 3 else we simply use input excluding int for prev version
if Factnum == 0: # for value 0, #factorial is 1 so we can straight end program here
print("Factorial is 1")
else:
print("Factorial of " ,fac2(Factnum)) #call recursive #function
