Java实现

public static void test03(){
        Scanner sc = new Scanner(System.in);
        String s = sc.nextLine();
        if (s.length() > 100) return;
        if (s.equals("")) {
            System.out.print(0);
            return;
        }
        String[] strings = s.split(" ");
        System.out.print(strings.length);
 }
