Fill in the line of the following Python code for calculating the factorial of a number.

def fact(num):

if num == 0:

return 1

else:

return _____________________

• num*fact(num-1)

• (num-1)*(num-2)

• num*(num-1)

• fact(num)*fact(num-1)

Observe the following Python code?

def a(n):

if n == 0:

return 0

else:

return n*a(n - 1)

def b(n, tot):

if n == 0:

return tot

else:

return b(n-2, tot-2)

• Both a() and b() aren’t tail recursive

• Both a() and b() are tail recursive

• b() is tail recursive but a() isn’t

• a() is tail recursive but b() isn’t

What will be the output of the following code snippet?

def thrive(n):

if n % 15 == 0:

print("thrive", end = “ ”)

elif n % 3 != 0 and n % 5 != 0:

print("neither", end = “ ”)

elif n % 3 == 0:

print("three", end = “ ”)

elif n % 5 == 0:

print("five", end = “ ”)

thrive(35)

thrive(56)

thrive(15)

thrive(39)

• five neither three thrive

• five neitherthrive three

• three three three

• five five
