      int n = sc.nextInt();
      String str = String.valueOf(n);
      String x1 = str.substring(0,1);
      String x2 = str.substring(1,2);
      String x3 = str.substring(2,3);
      if(x1.equals("1"))x1 = "9";
      else x1 = "1";

      else x3 = "1";
      String str1 = x1+x2+x3;
      int n1 = Integer.parseInt(str1);
