# Python program to check if the number is an Armstrong number with the index of 3 or not
# for input try numbers 153, 370, 371, 407

# take input from the user
num = int(input("Enter a number: "))

# initialize sum
sum = 0
# finding the length of num
n = len(str(num))

# find the sum of the cube of each digit
temp = num
while temp > 0:
   digit = temp % 10
   sum += digit ** n # power of n
   temp //= 10

# display the result
if num == sum:
   print(num, "is an Armstrong number.")
else:
   print(num, "is not an Armstrong number.")
