Students have asked these similar questions
in java, Two abstract data types are the ordered list and the unordered list. Explain how these two ADTs are similar and how they differ. To answer this question, assume that you do not know how they are implemented (that is, whether they are implemented using an array or a linked list).
Write a c 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 elementsin the queue and remove the elements of the queue and store these numbers according to thefollowing criteria.If the number in the queue is less than 50, remove it from the queue and store it insidequeue 2.Else, remove the number and store these values inside queue 3.Display all three queues on the screen.
d. In implementing a Queue using an array, a problem
might arise if the Queue is implemented in such a
way that items in the Queue are inserted at the next
available location and removed from the next leading
position, but such that, once deleted, the emptied
space is unused. The problem that arises is one
where there is free space still in the array, but it is not
usable because it is not at the end.
Demonstrate this problem with a Queue that is stored
in an array of size 5 for the following instructions.
Next, explain how you might resolve this problem.
Queue q
constructor takes 5 as the size of the array
= new Queue(5);
// assume the Queue
q.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 queue
q.enqueue(7);
// this enqueue can not
occur, why??

- Java design a Queue with O(1) lookup time of the Maximum element. You will implement this design using the ArrayDeque Class in Java. solve the problem as stated below:- (1) Here you will Maintain two Queues - a Main Queue and a Queue holding the Maximum value(s) from the Main Queue (AKA Max Queue). The Main Queue contains the elements. The Max Queue contains the elements with Maximum value. The Max Queue would have to be a double ended Queue as you would like to be able to remove elements from both ends. Example : Let’s say we have the following: We add an integer 1 into our Main Queue and I hope it is really obvious that when the Main Queue contains a single element, the Max Queue can be populated without confusion :) Main Queue: 1 << front of Queue Max Queue : 1 << front of Queue Now, let’s say we insert a 4 into the Main Queue. the Main Queue will look as follows: Main Queue: 4 → 1 << front of Queue In the Max Queue, we don’t need 1 anymore, since 1 can never…arrow_forwardIn a programming language (Pascal), the declaration of a node in a singly linked list is shown in Figure P6.7(a).

- you are to design a printer queue that is responsible for handling the printing requests coming from different users. You have to take into consideration that users have different levels of priorities. Each user has an identification number and a password, in addition to printing priorities. One good idea is to design the queue using an array or pointers while preserving the first-in first-out concept of the queue. For every printing request received, the program should check the priorities of that request and whether it can be moved forward in the queue to be served by the printer prior to serving the other requests. Using the programming language of your choice (preferably C++), write the printer queue that would handle the user request. The program must allow for requests coming from different users or from one user. Note: I need a working C++ code for this problem, and i need priorities.arrow_forwardWrite a complete Program in Java to implement circular queue using array for the following tasks: Method to insert the new element in the circular queue Method to delete an element from the circular queue Method to display all the elements of the circular queue Create the test class to perform the operations on circular queue in the following sequence: Add a new element 10 Add a new element 20 Add a new element 30 Add a new element 40 Display all elements Delete from the circular queue Delete from the circular queue Add a new element 50 Add a new element 60 Add a new element 70arrow_forwardThis is a java data structures question - Given a circular bent array-based queue capable of holding 100 objects. Suppose the queue is initially empty, and then objects are put into the queue at the rate of 10 per minute while meantime they are processed and removed from the queue at the rate of 5 per minute. After 120 elements have been added to the queue, which of the following is true? CIRCLE JUST ONE LETTER FOR THE ANSWER. -> You can’t add 120 elements to an array holding 100 entries. -> There will be 60 elements in the queue, 20 of them at the front of the array where the queue started, and 40 at the other end. -> There will be 60 elements in the queue, 30 of them at the front of the array where the queue started, and 30 at the other end. -> There will be 60 elements in the queue, 40 of them at the front of the array where the queue started, and 20 at the other end.arrow_forward
- A basic console program for car rental system is needed to be implemented by using linked list and tree in Java (Eclipse). The online rent a car system serves as a database storing available rental cars with their associated retailer. The system checks and shows a list of accessible rental cars to the user for a given time period. Then, they can book their desired car from the related store by using the program. The development language of the project is Java and 2 types of data structures are used: linked list and tree. All of the available option details of the cars are accumulated by linked lists and the customer information is stored in the tree.arrow_forwardAssume that a queue is implemented in C programming language using an array with size 15. At some point the front is at index 9 and rear (the last element) is 14.

- The Min-priority Queue is an abstract data type (ADT) for maintaining a collection of elements,each with an associated value called a key. The ADT supports the following operations:• INSERT(Q,x): insert the element x into the queue Q.• MIN(Q): returns the element of Q with the smallest key.• EXTRACT-MIN (Q): removes and returns the element of Q with the smallest key.Implement in Java the Min-priority Queue ADT defined above using a) an array based binary heap b) a binary search tree. Observe that the ADT implementation operations should be in the form q.insert(x),q.min(), etc. Explain in the report your implementation, noting the running time (using bigOh notation) of each operation in both implementations. c) What are the worst-case running times of the three ADT operations when theunderlying BST is self-balancing? Briefly explain your answer. d) Implement an extension of BST that allows MIN and EXTRACT-MIN operations in O(1). Briefly describe your implementation in the report. Hint:…arrow_forwardIn C++, develop an algorithm that adds the value val to a queue object Q. The queue is represented using an array data of size s. The algorithm should assume that the queue is not full. The most recently added item is at index r (rear), and the least recently added item is at index f (front). If the queue is empty, r = f = -1.arrow_forwardComputer Science Can someone help me create a program that is a library management system? So, the program will manage a library collection of books, allowing the user to add books, check them out, and return them. possibly use data structures such as linked lists or hash tables which will keep track of the availability of the books. demonstrate its function and discuss your experiences in creating it. Topics worthy of discussion include details of the implementation itself (language choice, class design, etc), difficulties that you faced in implementing it (learning new techniques, significant errors encountered, etc), and maybe a project post-mortem discussing whether or not you would do anything differently, knowing what you do about it at the end (e.g. using a linked list instead of an array). c++arrow_forward
