Question

true or false? when an object of class linkedqueue represents an empty queue, its rear variable is 0.

Answer 1

False. When an object of class LinkedQueue represents an empty queue, its rear variable is not 0. Instead, the front and rear pointers are set to null, indicating that there are no elements in the queue.

A LinkedQueue is a data structure that uses a linked list to implement a queue. In this implementation, the front and rear pointers are used to keep track of the first and last elements in the queue. When the queue is empty, both front and rear pointers are set to null, as there are no elements in the queue.
