给定酒店管理和用户的数据：
酒店数据：
Hotel Name Room Available Location Rating Price per Room
H1 4 Bangalore 5 100
H2 5 Bangalore 5 200
H3 6 Mumbai 3 100
用户数据：
User Name UserID Booking Cost
U1 2 1000
U2 3 1200
U3 4 1100
任务是回答以下问题。
- 打印酒店数据。
- 按名称对酒店进行排序。
- 按最高评价对酒店排序。
- 打印班加罗尔位置的酒店数据。
- 按可提供的最大客房数对酒店进行排序。
- 打印用户预订数据。
Machine coding round involves solving a design problem in a matter of a couple of hours.
It requires designing and coding a clean, modular and extensible solution based on a specific set of requirements.
方法：
- 为酒店数据和用户数据创建类。
- 初始化存储酒店数据和用户数据的变量。
- 为访问酒店数据和用户数据的酒店和用户类创建对象。
- 初始化两个向量数组，分别保存酒店数据和用户数据。
- 一一解决以上问题。
下面是上述方法的实现。
