Chapter 18, Problem 10RQE
Explanation of Solution
Queue:
- A queue contains sequence of items.
- The item which is inserted first, will be retrieved first.
- Queue performs “First In First Out”.
Operations performed on Queue:
A queue can perform two operations. They are:
- Enqueue
- Dequeue
Enqueue:
Insertion of an element into the queue is called as Enqueue...

It is a to the next node in the linked list, which is the property after it in the Node class.
You need to implement a class named "Queue" that simulates a basic queue data structure. The class should have the following methods:
Enqueue(int value) - adds a new element to the end of the queue
Dequeue() - removes the element from the front of the queue and returns it
Peek() - returns the element from the front of the queue without removing it
Count() - returns the number of elements in the queue
The class should also have a property named "IsEmpty" that returns a boolean indicating whether the queue is empty or not.
Constraints:
The queue should be implemented using an array and the array should automatically resize when needed.
All methods and properties should have a time complexity of O(1)
You can write the program in C# and use the test cases to check if your implementation is correct.
An example of how the class should be used:
Queue myQueue = new Queue();
myQueue.Enqueue(1);
myQueue.Enqueue(2);
myQueue.Enqueue(3);
Console.WriteLine(myQueue.Peek()); // 1…

Node
Node
front=
next
next=
next = nul1
rear =
data "Thome"
data "Abreu"
data - "Jones"
size - 3
The above is a queue of a waiting list. The ListQueue has a node (front)
to record the address of the front element of a queue. It also has another
node (rear) to record the address of the tail element of a queue.
4. How do you push a node with data, "Chu" to the above queue?
front.next = new Node("Chu", front);
a.
b.
front = new Node ("Chu", front)
rear = new Node("Chu", rear)
с.
d.
= new Node ("Chu", rear.next)
rear
Describe the reason of your choice.
Your answer is
(a, b, c, or d)
Will the push action take time in 0(1) or 0(n)?
