Difference between Stack and Queue Data Structures. Write down key differences. Write some code snippets. Draw images with some examples. Show differences for operations like push/pop, add/remove, etc.c++ Write a client function that returns the back of a queue while leaving the queue unchanged. This function can call any of the methods of the ADT queue. It can also create new queues. The return type is ITemType, and it accepts a queue as a parameter.
- A queue and a deque data structure are related concepts. Deque is an acronym meaning "double-ended queue." With a deque, you may insert, remove, or view from either end of the queue, which distinguishes it from the other two. Use arrays to implement a dequeA data structure called a deque is closely related to a queue. The name deque stands for “double-ended queue.” The difference between the two is that with a deque, you can insert, remove, or view from either end of the queue. Implement a deque using arraysRefer to the operations below:Add (10 + 5)Add (4+8)Add (7*2)Add (90 – 3)Print listPrint peekRemove an item from the listPrint list1.1 Implement the operations above into a Queue structure called q1. Name your program Question1_1 for the queue structure JAVA language to be used
- C++ Code for a QueueThe program should features a Queue class with insert(), remove(), peek(),isFull(), isEmpty(), and size() member functions.The main() program creates a queue of five cells, inserts four items, removes threeitems, and inserts four more. The sixth insertion invokes the wraparound feature. All the items are then removed and displayed. The output looks like this:40 50 60 70 80What Operations Can Be Performed On Queues?Answer the following by True or False: NOTE: When the question has been underlined, it requires two (2) answers. The ADT makes use of static array for its queue implementation. The class includes a constructor and destructor. A value must be provided when you initiate a dequeue operation.
- 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…A data structure called a deque is closely related to a queue.
