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.

In a program that uses several linked lists, what might eventually happen if the class destructor does not destroy its linked list?
QueueArray.java This file implements QueueInterface.java This file has * attributes of an array holding queue elements. An integer represents front * index, an integer for rear index, and an integer to keep track number of * elements in the queue. An overloaded constructor accepts an integer for * initializing the queue size, e.g. array size. An enqueue method receives an * object and place the object into the queue. The enqueue method will throw * exception with message "Overflow" when the queue is full. A dequeue method * returns and removes an object from front of the queue. The dequeue method * will throw exception with message "Underflow" when the queue is empty. A size * method returns number of elements in the queue. A toString method returns a * String showing size and all elements in the queue.

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.

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_forward
