初始化 roomsInUse 变量来记录当前正在使用的会议室数量。 遍历所有排序后的事件,每次遇到开始事件(1),就增加 roomsInUse;每次遇到结束事件(-1),就减少 roomsInUse。 同时,维护一个 maxRooms 变量来记录 roomsInUse 的最大值,即最大会议室数量。 时间复杂度: 事件拆分:我们有 N 个会议,每个会议生成两个事件...
For example, it returns 3 if there is only 3 characters left in the file. By using the read4 API, implement the function int read(char *buf, int n) that reads n characters from the file. Note: The read function will only be called once for each test case. 【...
