Dynamic Queue: DynamicQueue. A queue stores objects in an ordered list and allows insertions at one end and deletions from the other end of the list. The objects in this queue are stored in an array. The capacity of the array may be changed depending on the number of objects currently stored in the array, according to the following two rules: If an object is being inserted into the array is doubled. • If, after removing an object from a queue where the number of objects is one-quarter (1/4) the capacity of the array, then the capacity of the array is halved. The capacity of the array may not be reduced below the initially specified capacity. queue where the array is already full, the capacity of Description The aim of this project is to develop a dynamic queue. You will implement a queue using an array. The capacity of the array may be changed dynamically after insertions or deletions. For…

- Q/ In java language Create a Queue (capacity of 10 Students) of 6 different students according to their ID number De-queue one students and En-queue two Students by displaying their Front and Rear Values.ListQueue Node 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)? Next Page Type here to searchYou 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…
