C++
A queue is essentially a waiting list. It’s a sequence of elements with a front and a back. Elements can only be added to the back of the queue and they can only be removed from the front of the queue. Elements are kept in order so that the first element to enter the queue is the first one to leave it.

- 1 Implement a Queue Data Structure specifically to store integer data using a Singly Linked List. 2 The data members should be private. 3 You need to implement the following public functions: 4 1. Constructor: 5 It initialises the data members as required. 6 7 8 2. enqueue(data) : This function should take one argument of type integer.

- Problem Description: 1. Suppose that we want to add a method to a class of queues that will splice two queues together. This method adds to the end of a queue all items that are in a second queue. The header of the method could be as follows: public void splice (QueueInterface anotherQueue) Write this method in such a way that it will work in any class that implements QueueInterface.arrow_forwardYou 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…arrow_forwarddata structure-JAVAarrow_forward

Practice with use of Java exceptions. Practice use of generics. You have been provided with java code for SomeList<T> class. This code is for a general linked list implementation where the elements are not ordered. For this assignment you will modify the code provided to create a SortedList<T> class that will maintain elements in a linked list in ascending order and allow the removal of objects from both the front and back. You will be required to add methods for inserting an object in order (InsertInorder) and removing an object from the front or back. You will write a test program, ListTest, that inserts 25 random integers, between 0 and 100, into the linked list resulting in an in-order list. Your code to remove an object must include the exception NoSuchElementException. Demonstrate your code by displaying the ordered linked list and…arrow_forwardALL TRUE OR FALSE QUESTIONS 1. A "deque" allows an application to enqueue and dequeue from both front and rear of a queue. 2. The Queue ADT of the text is defined to hold elements of type Objec 3. Java supports inheritance of interfaces. 4. The text's array-based queue implementations use the fixed-front approach. 5. If N represents the number of elements in the queue, then the dequeue method of the ArrayBoundedQueue class is O(1). 6. When an object of class LinkedQueue represents an empty queue, its rear variable is 0. 7. A standard linked list provides a good implementation of a "Deque". 8. When implementing a queue with a linked list, the front of the queue is also the front of the linked list. 9. Our LinkedQueue class implements the QueueInterface interface. 10. The text's array-based queue implementations use the floating-front approach.arrow_forward
