- URGENT URGENT URGENT !!!! Write a void method swapStackwithQueue that takes MyStack and MyQueue Objects as parameters and exchanges the elements. a) The top element of the old stack becomes the rear element of the new queue. b b) and the rear element of the old queue becomes the top element of the new stack. The output should be similar to the image.Using python 1. Create a stack class using linked list. 2. Provide samples of push, pop; and 3. Using your new class, add a method that reverses a given string without using any built-in reverse methods. Use string below as an example. str_sample = 'Did Hannah see bees? Hannah did.' 4. Create a queue class using linked list. 5. Provide samples of enqueue, dequeue; and 6.Zack and Aerith are set to be married. Lined up in front of them will be the entourage of their closest friends composed of 5 pairs. Biggs and Jessie will march first. Announce their names by pair using queues (i.e. use print)! Make sure to use enqueue and dequeue methods! men = ['Zack', 'Cloud', 'Barret', 'Vincent', 'Cid', 'Biggs'] women = ['Aerith', 'Tifa', 'Marlene', 'Lucrecia', 'Yuffie', 'Jessie'] # Example # "Zack and Aerith!" # "Cloud and Tifa!"True or False? When implementing a queue with a linked list, the front of the queue is also the front of the linked list.
- Create a queue application with 1. an empty queue of integers 2. add numbers to the queue, 3. calculate and print the difference between the first and the last element. Example: Input : 2, 3, 4, 5, 6, 7, 8, 9 Output : 7 * Explanation: Last element is 9, first element is 2, the difference is 7You 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…Problem Description: Q1) Write a method public static void downsize (LinkedList employeeNames, int n) that removes every nth employee from a linked list. Q2) Write a method public static void reverse (LinkedList strings) that reverses the entries in a linked list.
- QUESTION 9 Write a complete Java program to implement a QUEUE in a bank using LinkedList class as follows: • Provide the menu as shown below; use an infinite loop; stop when user opts 4. 1. Add a customer 2. Remove a customer 3. Show the queue 4. Exit • Add a customer should add an int number at the end of queue using the method addLast(). • Remove a customer should delete the int from front using the method removeFirst(). Show the queue should display the numbers in queue using the method System.out.printIn(). For the toolbar, press ALT+F10 (PC) or ALT+FN+F10 (Mac).Please help create UML diagram for the java below. Thank you, the code is written below public class QueueUnderflowException extends Exception { QueueUnderflowException(){ super("Queue is empty."); } }For the Queue use the java interface Queue with the ArrayDeque classFor the Stack use the java Deque interface with the ArrayDeque classFor the LinkedList, use the java LinkedList class Also, when you are asked to create and use a Queue, you can use only those methods pertaining to the general operations of a queue (Enqueue: addLast, Dequeue: removeFirst, and peek() Similarly, when you are asked to create and/or use a stack, you can use only those methods pertaining to the general operations of a Stack (push: addFirst, pop:removeFirst, and peek() ) Your code should not only do the job, but also it should be done as efficiently as possible: fast and uses no additional memory if at all possible Questions Write a method “int GetSecondMax(int[] array)” . this method takes an array of integers and returns the second max value Example: if the array contains: 7, 2, 9, 5, 4, 15, 6, 1}. It should return the value: 9
- 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, 2 and 9. Show the instructions needed to move the value 2 in front of the value 5 so that the list is now 2, 5 and 9.Direction: Language is Python. Codes must have a function, output and comments. 1. Implement stack using queue. 2. Implement LinkedList using stacks.Please code in C language. Please use the starter code to help you solve the deleted node and the reverse list. Here is the starter code: #include <stdio.h> #include <ctype.h> #include <stdlib.h> #include <string.h> #include "linkedlist.h" // print an error message by an error number, and return // the function does not exit from the program // the function does not return a value void error_message(enum ErrorNumber errno) { char *messages[] = { "OK", "Memory allocaton failed.", "Deleting a node is not supported.", "The number is not on the list.", "Sorting is not supported.", "Reversing is not supported.", "Token is too long.", "A number should be specified after character d, a, or p.", "Token is not recognized.", "Invalid error number."}; if (errno < 0 || errno > ERR_END) errno = ERR_END; printf("linkedlist: %s\n", messages[errno]); } node *new_node(int v) { node *p =…
