- 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 dequeYou have a sorted linked list. Fill in the missing code in the following function. SortedType::DeleteItem(Item Type item) // pointer delete //trailing pointer // traveling pointer void { NodePtr tempPtr; NodePtr predLoc; NodePtr location: bool found false; // Find item to delete: Put your code below //delete item: Put your code belowYou can access any element on a queue. True False
- Given a pointer based queue below: Andy Max Suzy Shah Bob Hal Ted Assuming the front is on Andy and the rear is on Ted, what is the result of enqueueing Lisa and dequeueing one element? Select one: a. Max Suzy Shah Bob Hal Ted Lisa b. Lisa Max Suzy Shah Bob Hal Ted c. Andy Max Suzy Shah Bob Hal Lisa d. Lisa Andy Max Suzy Shah Bob HalA 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 arraysListQueue Node Node Node front- next = next next - nul1 data - "Jones" rear data "Thome" data - "Abreu" 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. 3. How do you pop a node from the above queue? a. front.next = front; b. front = front.next с. rear = rear.next d. rear.next = rear Describe the reason of your choice. Your answer is (a, b, c or d) will the pop action take time in 0(1) or 0(n)? Next Page P Type here to search
- In the array based queue the serve method set the front to front + 1 Select one: True FalseModify the given code to make it work using the keywords (undo,redo,display and exit) instead of the case statment. It will insert by default but when it reads one of the keywords it will go the function we call.

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 search
- 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…In C, members (fields) of different structures can have the same name.
