class MyCalendar {

    private List<int[]> list;

    public MyCalendar() {
        list = new ArrayList<>();
    }
    
    public boolean book(int startTime, int endTime) {
        for (int[] time : list) {
            if (time[0] < endTime && startTime < time[1]) {
                return false;
            }
        }

        list.add(new int[]{ startTime, endTime });
        return true;
