Apex VO 面试真题解析：Meeting Room Scheduler 会议室预约系统

Problem: Meeting Room Scheduler

Background:

A company has multiple meeting rooms. Employees want to book these rooms for meetings. Your task is to build a simple meeting room scheduler.

Requirements:

Implement a class-based system for managing meeting room bookings.

Each room has:

• A unique name.
• A capacity.

A booking has:

• A meeting room.
• A start time and end time.
• A list of attendees.

这道题要求实现一个基于类的会议室预约系统，核心是把“会议室”和“预订”这两个实体建模清楚：会议室通常包含唯一名称和容量，预订则包含所属会议室、开始时间、结束时间以及参会人列表。解题时重点在于设计数据结构并维护会议室的占用状态，判断新预约与已有预约是否时间重叠，同时还要考虑容量是否足够容纳参会人数。
