Question

Input a number and verify whether it is an Armstrong number or not. A number is called a Armstrong Number if the number is equal

to the sum of cube of each digit of the number. 153 = 1

3+53+33 = 1+125+27​

Answer 1

You can use the following python code:

num = input('Enter a number: ')

def checkArmstrong(num):

sum = 0

for i in str(num):

sum += (int(i) ** 3)

if sum == int(num):

return True

else:

return False

print(checkArmstrong(num))

This is written in Python.

n=int(input("Enter a number: "))

x, s=n, 0
