    Solution

        public static String getSmallestAndLargest(String s, int k) {
        String smallest = "";
        String largest = "";
        int i = 0;
        smallest = s.substring(0, k);  
        largest = s.substring(0, k);   
            
        while (i < s.length()-k){
            String tmp = s.substring(i+1, i+k+1);
            
            if (tmp.compareTo(smallest)<0){
                smallest = tmp;
            }
            if(tmp.compareTo(largest)>0){
                largest = tmp;
            }
            i++;
        }
        return smallest + "\n" + largest;
