//inteface i11 
 public interface i11
    {
        void m11();
    }
//interface i22
    public interface i22
    {
         void m11();
    }

//class ab implements interfaces i11 and i22
    public class ab : i11, i22
    {
        public void m11()
        {
            Console.WriteLine("class");
