- Answer it fast and correct. Don't stuck. i ll rate Fill in the underlines below to complete a function template, reverseStack, that takes as a parameter a stack object and uses a queue object to reverse the elements of the stack. C++ code Answer: template <class Type> void reverseStack(stackType<Type> &s) { linkedQueueType<Type> q; Type elem; while (_________________) // The stack is not empty. { // Copy the top element of the stack into the queue //and remove it from the stack. elem = _________________; _________________; _________________; } while (_________________) // The queue is not empty. { // Copy the front element of the queue into the stack //and remove it from the queue. elem = _________________; _________________; _________________; } }The ADT stack lets you peek at its top entry without removing it. For some applications of stacks, you also need to peek at the entry beneath the top entry without removing it. We will call such an operation peek2. If the stack has more than one entry, peek2 returns the second entry from the top without altering the stack. If the stack has fewer than two entries, peek2 throws an exception. Write a linked implementation of a stack class call First_Last_LinkStack.java that includes a method peek2The ADT stack lets you peek at its top entry without removing it. For some applications of stacks, you also need to peek at the entry beneath the top entry without removing it. We will call such an operation peekNxt. If the stack has more than one entry, peekNxt returns the second entry from the top without altering the stack. If the stack has fewer than two entries, peekNxt throws an exception.

Inside the method, you may create exactly one temporary container -- either a stack or a queue. It is alright to create variables of primitive data types (such as, an integer), if required. You must use the following header. public void reverse(Stack s){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!"
- Implement a method transfer in class LinkedStack. This method should transfer all elements of a stack sourceS to another stack targetS so that the element that starts at the top of sourceS is the first one to be inserted in targetS, and the element at the bottom of sourceS ends up at the top of targetS. The operation should result in sourceS being an empty stack. Test this method in the main method of LinkedStack. package stacks;public class LinkedStack<E> implements Stack<E> {/** The primary storage for elements of the stack */private SinglyLinkedList<E> list = new SinglyLinkedList<>(); // an empty list/** Constructs an initially empty stack. */public LinkedStack() { } // new stack relies on the initially empty list@Overridepublic int size() { return list.size(); }@Overridepublic boolean isEmpty() { return list.isEmpty(); }@Overridepublic void push(E element) { list.addFirst(element); }@Overridepublic E top() { return list.first(); }@Overridepublic E pop() {…A double-ended queue or deque is a generalization of a stack and a queue that supports adding and removing items from either the front or the back of the data structure. This assignment has two parts: Part-1 Create a doubly linked list based DeQueDLL class that implements the DequeInterface. The class skeleton and interface are provided to you. Implement a String toString () method that creates and returns a string that correctly represents the current deque. Such a method could prove useful for testing and debugging the class and for testing and debugging applications that use the class. Assume each queued element already provides its own reasonable toString method. Part-2 Create an application program that gives a user the following three options to choose from – insert, delete, and quit. If the user selects ‘insert’, the program should accept the integer input from the user and insert it into the deque in a sorted manner. If the user selects ‘delete’, the program should…TRUE or FALSE? Answer the following question and state the reason why: A circular linked list has 2 node pointers. cout<<list.back()<<endl; = The back member function returns a reference to the last element in the list. In a Dynamic Stack, the pointer top stays at the head after a push operation. During a Pop operation in Static Stack, the elements are being moved one step up. In a dynamic implementation of stack, the pointer top has an initial value of null.
- The minimum number of stacks are needed to implement a queue is. Consider the situation where no other data structure like arrays, linked list is available to you. a. Three b. One c. Four d. TwoGiven the following stack A = {29, 18, 10, 15, 20, 9, 5, 13, 2, 4, 15} Create a queue by taking the elements from the top of the stack and adding them to the queue.Implement Stack using Queues The Stack class should support the following methods: int size() boolean isEmpty() int top() void push(int element) void pop() You can assume that you've access to a Queue class which provides the following methods: int size() boolean isEmpty() int front() int back() void push(int element) void pop()
