Stack stores elements in an ordered list and allows insertions and deletions at one end. The elements in this stack are stored in an array. If the array is full, the bottom item is dropped from the stack. In practice, this would be equivalent to overwriting that entry in the array. And if top method is called then it should return the element that was entered recently.
Project Description: In this project you implement an ArrayStack ADT and use the stack for implementing the following methods: a) Reverse an array of Words: Accept an array of words as input parameter and return an array of words in reverse order. Use the method signature: public static String[] reverseWords (String[] wordList) Example Input: Bird Cat Dog Elephant Output: Elephant Dog Cat Bird
6. Given a Stack of holding 7 objects. Show the final contents of the array after the following code is executed: for (int k = 1; k <= 7; k++) S.Push(k); for (int k = 1; k<= 4; k++) { S.Push(S.Pop()); S.Pop(); }
Min Heap of Candy — Add and Remove Using the provided code (Question04.java and Candyjava), write the add and remove methods for a min heap of Candy using an array implementation. Make sure to include all provided files in your project and write your solution in the file "Question04.java". This method should preserve the properties of a min hap, and the candies are compared based on their weight. This value can be accessed through its accessor. Solution Tests: • Does the solution compile? • Does the solution have your name in the comments? • Does the solution have a high-level solution description (150-300 words) in the comments? • Does the method preserve the properties of a Min Heap? • Does the output match the following? Testing the Add Method Candy Weight: 10.0, Candy Weight: 40.0, Candy Weight: 20.0, Candy Weight: 50.0, Candy Weight: 60.0, Candy Weight: 80.0, Candy Weight: 30.0, Candy Weight: 100.0, Candy Weight: 70.0, Candy Weight: 90.0, Testing the Remove Method Candy Weight:…
Java Implement Stack using Deque (doubly linked list) You must create an array and the user can insert elements into this array and can only access or remove the newly inserted element from the array. The array is executed using a doubly linked list. The following Project should have these classes: 1. Class Book: The main Node for the deque array where it should have the following attributes besides (next, prev nodes): a) Book Id b) Book Name c) Book Author 2. Class Booklists: Where all the main operations are done. You need to apply these following operations: 1) AddBook() [push(0) : The method Inserts the book object into deque Stack (form the last). 2) RemoveBook() [pop()] : This method extracts an object from the last of the Deque stack and it removes it. If such object does not exist, the method returns null.(from the last) 3) isEmpty() : Return True if deque stack is Empty else return False. 4) DisplayAlIBooks() : Print all the books in the deque stack. 5) getlistsize(): Return…
Write a program and fill a queue with random numbers between 0 and 100. The size of thequeue is assumed to be 15. After filling the array with random numbers, display the elements in the queue and remove the elements of the queue and store these numbers according to the following criteria.If the number in the queue is less than 50, remove it from the queue and store it inside queue 2.Else, remove the number and store these values inside queue 3.Display all three queues on the screen.

java program: University of Bahrain College of Information Technology Department of Computer Science Second Semester, 2020-2021 ITCS214 / ITCS215 / ITCS216 (Data Structures) Assignment 3 Implement generic class ArrayStack as discussed in the lectures having following methods: constructor, push, pop, peek, isEmpty, copy constructor, reallocate (private method). Also add following methods to this class: size: returns number of elements in the stack. contains: Search an element in the stack. If found returns true, else returns false. clear: Deletes all elements of the stack and make it empty stack. Implement generic class ArrayQueue as discussed in the lectures having following methods: constructor, copy constructor, offer, poll, peek, isEmpty, reallocate(private), iterator. Inner class Iter that implements interface Iterator having methods: constructor, hasNext, next. Also add following methods to the ArrayQueue class: size: returns number of elements in the queue. contains: Search…
I have implemented a stack using arrays. The array is 5 elements long and is called examstack. The contents are: examstack[0] = 36 examstack[1] = 49 examstack[2] = 7 examstack[3] = 67 examstack[4] = 9 If I did a Pop what would be returned? 9 or 36 09 07 O 67 O 9 or 67 36 or 49 O 36 49
A stack is a collection of objects that are inserted and removed using Last in First out Principle (LIFO). User can insert elements into the stack, and can only access or remove the recently inserted object on top of the stack .In this following project, you will implement stack using doubly linked list(deque) as it was explained in the previous lectures.The following Project should have these classes:1. Class Book: The main Node for the deque stack where it should have the following attributes besides (next, prev nodes):a. Book Idb. Book Namec. Book Author2. Class BookLists: Where all the main operations are done.Note: you can add more classes if you want but must include the main ones.You need to apply these following operations: 1. AddBook() [push()] : The method Inserts the book object into deque Stack (form the last).2. RemoveBook() [pop()] : This method extracts an object from the last of the Deque stack and it removes it. If such object does not exist, the method returns…
