    Find no answer without solving:

        ArrayList<Character> s = new ArrayList<Character>();
    ArrayList<Character> o = new ArrayList<Character>();
    int l = w.length();
    for(int i = 0; i < l; i++){
        s.add(w.charAt(i));
    }
    o = (ArrayList<Character>)s.clone();
    Collections.sort(s, Collections.reverseOrder());

    if(o.equals(s)){
        return "no answer";
    }

    Then solve using lexicographical permutation algorithm
