public static void mystery(Map<String, String> map) {
    Map<String, String> result = new TreeMap<String, String>();
    for (String key : map.keySet()) {
        if (key.compareTo(map.get(key)) < 0) {
            result.put(key, map.get(key));
        } else {
            result.put(map.get(key), key);
        }
    }
    System.out.println(result);
}
{two=deux, five=cinq, one=un, three=trois, four=quatre}
