a.What are the siblings of node homeworks/?

b.Which nodes are in the subtree rooted at node projects/?

c. What is the depth of node papers/?
d.  What is the height of the tree?

This diagram illustrates a structured directory hierarchy beginning at the top with `/user/rt/courses/`. It is divided into two main branches representing different courses: `cs016/` and `cs252/`.

### Branch 1: `cs016/`
- **grades**
- **homeworks/**
  - `hw1`
  - `hw2`
  - `hw3`
- **programs/**
  - `pr1`
  - `pr2`
  - `pr3`

### Branch 2: `cs252/`
- **grades**
- **projects/**
  - **papers/**
    - `buylow`
    - `sellhigh`
  - **demos/**
    - `market`

This hierarchy shows the organization of files and folders for two courses, with subcategories for different types of course materials such as grades, homeworks, programs, projects, papers, and demos.
