        for (i=0; i < l-1; i++) {
            r = er.charAt(i);
            if (r == ' ') {
                for (oy=i; oy < i+1; oy++) {
                    n = er.charAt(oy);
                    System.out.println(n + " ");

    {
        InputStreamReader cr = new InputStreamReader(System.in);
        BufferedReader in = new BufferedReader(cr);
        int i, oy,l;
