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…
The data structure that allows for elements to be added and removed at both ends but not in the middle is called:
1.Double-ended Queue.
2.Priority Queue.
3.Duck.
4.Torque.
