Question

Write a program to input any number and check whether given number is Armstrong or not.

Answer 1

For a three-digit Armstrong number, add the cubes of its digits and compare the sum with the original number.

n = int(input("Enter any number: "))
original = n
sum_of_cubes = 0

while n > 0:
    digit = n % 10
    sum_of_cubes += digit ** 3
    n //= 10

if sum_of_cubes == original:
    print("Armstrong number")
else:
    print("Not an Armstrong number")
