请实现一个 MyCalendar 类来存放你的日程安排。如果要添加的时间内没有其他安排,则可以存储这个新的日程安排。

\n\n

MyCalendar 有一个 book(int start, int end)方法。它意味着在 start 到 end 时间内增加一个日程安排,注意,这里的时间是半开区间,即 [start, end), 实数 x 的范围为,  start <= x < end

\n\n

当两个日程安排有一些时间上的交叉时(例如两个日程安排都在同一时间内),就会产生重复预订。

\n\n

每次调用 MyCalendar.book方法时,如果可以将日程安排成功添加到日历中而不会导致重复预订,返回 true。否则,返回 false 并且不要将该日程安排添加到日历中。

\n\n

请按照以下步骤调用 MyCalendar 类: MyCalendar cal = new MyCalendar(); MyCalendar.book(start, end)

\n\n

 

\n\n

示例:

\n\n
\n输入:\n["MyCalendar","book","book","book"]\n[[],[10,20],[15,25],[20,30]]\n输出: [null,true,false,true]\n解释: \nMyCalendar myCalendar = new MyCalendar();\nMyCalendar.book(10, 20); // returns true \nMyCalendar.book(15, 25); // returns false ,第二个日程安排不能添加到日历中,因为时间 15 已经被第一个日程安排预定了\nMyCalendar.book(20, 30); // returns true ,第三个日程安排可以添加到日历中,因为第一个日程安排并不包含时间 20 \n
