a.run();

}

What will be the output of the following code?

class A

    {

        int rec (int n) 

        {

            int count;

            count = rec (n - 1);

            return count;

        }

    } 

class B

{

    public static void main(String args[]) 

    {

        A obj = new A() ;

        System.out.print(obj.rec(12));

    }

}

  import java.util.*;

    class output 

    {

        public static void main(String args[]) 

        {

            TreeSet obj = new TreeSet();

            obj.add("5");

            obj.add("2");

            obj.add("3");

            obj.add("1");

obj.add("9");

obj.add("3");

obj.add("2");

            System.out.println(obj + " " + obj.size());

        }

    }
