Implement in Python a double-ended queue (deque): A double-ended queue is a data structure (ordered collection of items) similar to a traditional queue. It has two ends, front and end, but it is not restricted to adding or removing items. New items can be added on the front or on the end. Existing items can be removed from either end. The image graphically shows how the structure is. - Implement the requested structure using a single linked list, which implements the following functions: enterFront, enterEnd, removeFront, removeEnd - The data to be entered are animal-type objects; name, type of animal, age - Create a Main function with the available operations

Implement a Queue using a vector or the STD ::queue:: class Note the difference in what it takes to implement using a char[] array vs a vector or the STD ::queue:: class The user will input a string and the program will return the string with each letter in the string duplicated. Displaying correct Queue implementation. Utilize the conventional methods as needed. Sample Execution Please input String: happy Program will produce the output string. Only use the enqueue(), dequeue(), empty(), etc hhaappyy

In C++ Prepare a queue program for numbers using a menu with the operations: insert, del, display. Consider the size of the queue is 10. The display operation will show the numbers that are in the queue. Hint: OPERATIONS: insert 10,20,30, display them, delete from queue , display the queue .  r=-1, f=-1

Create a programme that sorts a stack so that the smallest elements appear on top. You can use a second temporary stack, but you can't transfer the components into another data structure (such an array). The following operations are supported by the stack: push, pop, peek, and is Empty.

BankCustomerQueueADT Implement in C++ a BankCustomer QueueADT that does the following: 1. gets the input about a customer (first name, last name, Bank Account Number, Money to be withdrawn/deposited, etc.) from the user (from the keyboard) 2. inserts (enqueues) the Customer as a record into the BankCustomerQueueADT (your Queue ADT must be able to have a maximum of 20 customer records) 3. removes (dequeues) the Customer record from the BankCustomerQueueADT 4. your BankCustomerQueueADT must also have the behavior of retrieving and displaying the Queue info on the screen after each event (either entry of a Bank Customer into the queue, OR leaving of the Bank customer from the queue). NOTE: Please make sure you debug, run, test and see the program working correctly before submitting. Make sure all the code statements are commented. Make sure your program is indented properly.

In java The following is a class definition of a linked list Node:class Node{int info;Node next;}Assume that head references a linked list and stores in order, the int values 5, 7 and 9.  Show the instructions needed to delete the Node with 5 so that head would reference the list 7 and 9.

A is a structure that allows multiple connections between the objects (Select the BEST answer) O a. queue O b. graph O c. linked list O d. tree O e. stack

The queue operation that is required when using an array implementation, but is not required when using a linked list implementation, is ___. isFull() isEmpty() peek() dequeue()

Java Algorithm Programming Question Implement the ADT queue by using a circular linked list. Recall that this list has only an external reference to its last note. Example Output: Create a queue: isEmpty () returns true Add to queue to get Joe Jess Jim Jill Jane Jerry isEmpty () returns false Testing getFront and dequeue: Joe is at the front of the queue. Joe is removed from the front of the queue. Jess is at the front of the queue. Jess is removed from the front of the queue. Jim is at the front of the queue. Jim is removed from the front of the queue. Jill is at the front of the queue. Jill is removed from the front of the queue. Jane is at the front of the queue. Jane is removed from the front of the queue. Jerry is at the front of the queue. Jerry is removed from the front of the queue. The queue should be empty: isEmpty() returns true Add to queue to get Joe Jess Jim Testing clear: isEmpty() returns true Add to queue to get Joe Jess Jim Joe is at the front of the queue. Joe is…
