Workday VO 面试真题解析：National Park – BPC（图查询与系统建模）

National Park – BPC

Definition:

We are building a system that can track the campgrounds at a National Park as well as the attractions available for guests.

Exercise 1:

For a National Park, we want to know:

• What are the campsites at the park?
• How many rangers work at the park?
• What’s the phone number of Ranger Smith?

这道 Workday VO 题目本质上是在考察如何把“国家公园”建模成可查询的数据结构，并支持按类别检索信息。题干要求我们维护营地、景点和 ranger 等对象，然后回答诸如“有哪些 campsites”“有多少 rangers”“Ranger Smith 的电话号码是多少”这类查询，适合用面向对象设计或哈希映射来组织数据，再结合遍历与筛选完成检索。
