public static string findGholi(int n)
        {
            int r=0;
            int number = n;
            while(number > 0)
            {
                int temp = number % 10;
                r = (r * 10) + temp;
                number = number / 10;
            }
            if (n == r)
                return n.ToString() + " is correct";
            return n.ToString() + " is not correct";
        }
