Expert Solution & Answer
Chapter 17.1, Problem 1SCP
Explanation of Solution
Number of roots in a tree:
- A tree is constructed using nodes.
- The topmost node in a tree is referred as root of the tree...
Explanation of Solution
Branches or leaves in a tree:
“Yes”, a tree can have more branches or leaves.
Explanation:
- Consider a perfect binary tree of height “3”, in which a number of leaves is greater than the branches.
- Hence, a tree can have more branches than leaves...

Question3: (30 MARKS) Passenger Rail Agency for South Africa Train Scheduling System Problem Statement Design and implement a train scheduling system for Prasa railway network. The system should handle the following functionalities: 1. Scheduling trains: Allow the addition of train schedules, ensuring that no two trains use the same platform at the same time at any station. 2. Dynamic updates: Enable adding new train schedules and canceling existing ones. 3. Real-time simulation: Use multithreading to simulate the operation of trains (e.g., arriving, departing). 4. Data management: Use ArrayList to manage train schedules and platform assignments. Requirements 1. Add Train Schedule, Cancel Scheduled Train, View Train Schedules and Platform Management 2. Concurrency Handling with Multithreading i.e Use threads to simulate train operations,…
