练习使用 ArrayList

for(int i = 0; i< 13; i++){
    list.add(0,remove(4));
}

        ArrayList<String> list = new ArrayList<>();
        Scanner scanner = new Scanner(System.in);
        int max = Integer.MIN_VALUE;
        int min = Integer.MAX_VALUE;
        for (int i = 0; i < 10; i++) {
            list.add(scanner.next());
            max = Math.max(max, list.get(i).length());
            min = Math.min(min, list.get(i).length());
        }

        for (int i = 0; i < list.size(); i++) {
            if (list.get(i).length() == max || list.get(i).length() == min){
                System.out.println(list.get(i));
                break;
            }
        }
