class Result 
{
 
        public static int num(int ...x)
        {
             return; 
        }
        static void main(String args[]) 
        {    
             num(10);
             num(10,20);
             num(10,20,30);
             num(10,20,30,40);
        } 
}

1. only num(10,20)
2. only num(10)
3. only num(10) & num(10,20)
4. all of the mentioned
