        number = int.Parse(Console.ReadLine());

        temp = number;
        while (temp > 0)
        {
            digit = temp % 10;
            sum += digit * digit * digit;
            temp /= 10;
        }

        if (number == sum)
        {
            Console.WriteLine(number + " is an Armstrong number.");
        }
        else
        {
