Program:

//define the static function

public static void mystery(Map<String, String> map) {

    //create a map

    Map<String, String> result = new TreeMap<> ();

    //loop initialized to print the key

    for (String key : map.keySet()) {

        //condition initialized to compare the key value

        if(key.compareTo(map.get(key))<0) {

            //map the keys

            result.put(key, map.get(key));

        }else {

            //map the keys

            result...
