        int len = (int)Math.Log10(num) + 1;
        float sum = 0.0f;
  
        int temp = num;
        while (temp > 0) {
            remainder = temp % 10;
            sum = sum + (int)Math.Pow(remainder, len);
            temp = temp / 10;
            len--;
        }
 
        if (num == (int)sum)
            Console.Write("{0} is a disarium number", num);
