        {
            int hld;
            while(y !=0)
            {
                hld = x & y;
                x = x ^ y;
                y = hld << 1;
            }
            return x;
        }
        static void Main(string[] args) 
        {            
            int a, b, sum;
            Console.WriteLine("Enter Two Numbers ");
            a = int.Parse(Console.ReadLine());
            b = int.Parse(Console.ReadLine());
            sum = add(a, b);
            Console.WriteLine("Sum = " + sum);
        }
    }
