Chapter 20, Problem 1MC
Program Description Answer
A Queue is a linear data structure in which items are accessed first-in-first-out fashion.
Hence, the correct answer is option “B”.
Expert Solution & Answer
Explanation of Solution
Queue:
- Queue is a linear data structure used to store a set of data.
- Queue is the collection of data which are accessed in FIFO (first-in-first-out) order for performing operations on it.
- Queue is opened at both the ends. One end to insert the items into the queue and the other end is to remove the items from the queue.
- There are two basic operations on queue data structure,
- enqueue() – add an item to queue.
- dequeue() – remove an item from the queue.
- Queue does not have fixed size.
Explanation for incorrect options:
A. Stack
A stack is used to store set of data that are accessed in last-in-first-out order.
Hence, option “A” is wrong.
C. Linked list
A linked list is a collection of data items. This stored item is accessed in random order for doing operations on it.
Hence, option “C” is wrong.
D. Array based collection
An array based collection (simply array) used to store set of items. Each stored item is accessed using array index or key.
Hence, option “D” is wrong.

- Description The aim of this project is to develop a cyclic doubly linked list. You will implement two classes: 1. Cyclic doubly linked lists: CyclicDoubleList, and 2. Doubly linked nodes: DoubleNode. A cyclic doubly linked list with three nodes is shown in Figure 1. The empty cyclic doubly linked list is shown in Figure 2. head. Figure 1. A cyclic doubly linked list and three nodes. head- Figure 2. An empty cyclic doubly linked list. The class CyclicDoubleList stores a finite list of n (zero or more) elements stored in doubly linked nodes. If there are zero elements in the list, the list is said to be empty. Each element is stored in an instance of the DoubleNode class. If the list is empty, the head pointer points to null. Otherwise, the head pointer points to the first node, the next pointer of the ith node (1 referred to as the head pointer, and An integer referred to as the list size which equals the number of elements in the list.

- Question 2: Linked List Implementation You are going to create and implement a new Linked List class. The Java Class name is "StringLinkedList". The Linked List class only stores 'string' data type. You should not change the name of your Java Class. Your program has to implement the following methods for the StringLinked List Class: 1. push(String e) - adds a string to the beginning of the list (discussed in class) 2. printList() prints the linked list starting from the head (discussed in class) 3. deleteAfter(String e) - deletes the string present after the given string input 'e'. 4. updateToLower() - changes the stored string values in the list to lowercase. 5. concatStr(int p1, int p2) - Retrieves the two strings at given node positions p1 and p2. The retrieved strings are joined as a single string. This new string is then pushed to the list using push() method.arrow_forwardExplain the differences between a statically allocated array, a dynamically allocated array, and a linked list.arrow_forwardAn Iterator to a list object that stores Integer objects can be created as follows Iterator itr = new Iterator(), Iterator itr = list.iterator(), Iterator itr = new Iterator(); Iterator itr = new Iterator ().arrow_forward
