Expert Solution & Answer
Chapter 20, Problem 10TF
Program Description Answer
In linked list implementation of queue, the “front” and “rear” will be pointing to the same element if there is only one element in the queue and also when the queue does not have any values.
Hence, the given statement is “False”.

The name “Deque" comes from "double-ended queue" and is usually pronounced "deck". Like the Stack and the Queue, a Deque permits elements to be accessed only at the ends. However, a Deque allows items to be added at either end and removed from either end. We can refer to the operations supported by the Deque as enqueueFront, enqueueRear, dequeueFront, and dequeueRear. Note that once you have a Deque, you can use it to implement both the Stack and the Queue. Implement the Deque using a dynamic, linked implementation (15pts) Use your Deque to implement a Stack (15pts). Use your Deque to implement a Queue (15pts). Test your implementation across the 3 data structures to tell the story of your work (10pts).arrow_forward
