Objectives: The code for the different stack and queue operations in both implementations (array and linked list) are discussed in the lectures: and are written in the lectures power point. So the main object of this assignment is to give the student more practice to increase their understanding of the different implementation of these operations. - The students also are asked to write by themselves the main methods in the different exercises below; The Lab procedures: The following files must be distributed to the students in the Lab - arrayImpOfStack.java // it represents an array implementation of the stack. - pointerImOfStack.java // it represents a Linked List implementation of the stack. - pointerImOfQueue.java // it represents a pointer implementation of the queue. Then the students by themselves are required to write the code for the following questions Ex1) Given the file arrayImpOfStack.java then write a main method to read a sequence of numbers and using the stack…
Suppose that queue is implemented as an array with the special reserved slot, as described in this chapter. Also, suppose that the size of the array implementing queue is 100. If the value of queueFront is 50, what is the position of the first queue element?
StackQueuePostfix A. Pointer_based queuea. Define the class PoiQueue with no implementation; i.e. declare the datamembers, and the function members only (Enqueue, Dequeue, IsEmpty,GetHead etc.).b. Implement the Enqueue method of the above classB. Array_based non-circular queue:a. Define the class Queue using one dimensional array representation with noimplementation; i.e. declare the data members, and the function membersonly (Enqueue, Dequeue, IsEmpty, GetHead etc.).b. Implement the Denqueue method of the above class
Both array lists and linked lists are examples of how a list may be implemented. Discuss a scenario when a linked list might be preferable than a list stored in an array. Explain your reasoning in each situation.
Consider the Queue ADT: Queue: enqueue(x) adds x to the back of the queue dequeue () removes element at the front of the queue size() returns number of elements in queue Select all options that allow for an efficient implementation based on the discussions from class. For any array implementation, you can assume the array is large enough so that making a larger one is not needed when pushing an item to the stack. You can assume that a linked list will have both a head and tail reference. Using an array with the front of the queue at the front of the array. Using an array with the front of the queue at the back of the array. Using a singly linked list with the front of the queue at the head of the list. Using a singly linked list with the front of the queue at the tail of the list. None of these choices allows for an efficient implementation of all methods.
For example: Programming generates and modifies linked lists: Typically, the software monitors two nodes: How to utilise the null reference in the node of a linked list in two common scenarios.
ALL TRUE OR FALSE QUESTIONS 1. The text's array-based queue implementations use the fixed-front approach. 2. The enqueue and dequeue queue operations are inverses of each other. Therefore, performing an enqueue followed by a dequeue is always equivalent to performing a dequeue followed by an enqueue. 3. It is possible to implement an unbounded queue using an array-based approach. 4. Our QueueInterface defines two constructors. 5. The isEmpty operation as defined for the text's Queue ADT might throw the QueueUnderflowException. 6. A "dequeue" allows an application to peek at the front of rear values of a queue. 7. A java interface can inherit from at most one other interface. 8. The main thread of a Java program cannot generate additional threads. 9. Code sequences in concurrent programs never interfere with each other.

(a) In implementing a Queue using an array, a problem might arise if the Queueis implemented in such a way that items in the Queue are inserted at thenext available location and removed from the next leading position, butsuch that, once deleted, the emptied space is unused. The problem thatarises is one where there is free space still in the array, but it is not usablebecause it is not at the end.Demonstrate this problem with a Queue that is stored in an array of size 5for the following instructions. Next, explain how you might resolve thisproblem.Queue q = new Queue(5); // assume the Queue constructor takes 5 asthe size of the arrayq.enqueue(3);q.enqueue(4);q.enqueue(1);q.dequeue( );q.dequeue( );q.enqueue(6);q.enqueue(5);q.dequeue( ); // at this point,// there are only 2 item2 in the queueq.enqueue(7); // this enqueue cannot occur, why??
