import java.util.*;

class Solution {
    public String[] solution(String myString) {
        StringTokenizer st = new StringTokenizer(myString, "x");
        ArrayList<String> arrList = new ArrayList();

        while(st.hasMoreTokens()) {
            arrList.add(st.nextToken());
        }


        Collections.sort(arrList);

        String[] answer = arrList.toArray(new String[arrList.size()]);
        return answer;
    }
}
