   int n, temp;

   BufferedReader in=new BufferedReader(new  InputStreamReader(System.in));

   int arr[]=new int[30];

    try

    {

      n=Integer.parseInt(in.readLine());

     for(int i=0;i<n;i++)

      {

      }

      System.out.println("Unsorted array list:");

      for(int i=0;i<n;i++)

      {

              arr[j]=temp;

             }

           }

        }    

        System.out.println();

        System.out.println("Sorted array list:");
