static class Reader {
        public BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        public StreamTokenizer st = new StreamTokenizer(br);

        public void token() {
            try {
                st.nextToken();
            } catch (IOException e) {}
        }
