d. In implementing a Queue using an array, a problemmight arise if the Queue is implemented in such away that items in the Queue are inserted at the nextavailable location and removed from the next leadingposition, but such that, once deleted, the emptiedspace is unused. The problem that arises is onewhere there is free space still in the array, but it is notusable because it is not at the end.Demonstrate this problem with a Queue that is storedin an array of size 5 for the following instructions.Next, explain how you might resolve this problem.Queue qconstructor takes 5 as the size of the array= new Queue(5);// assume the Queueq.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 item2in the queueq.enqueue(7);// this enqueue can notoccur, why??

the code is given below : public class Queue{private int front,rear,data,x[],size; public Queue(int…

How to answer the following questions screen shot show the text's arrayboundedqueue and the array unbounded queue The text's array-based queue is being used and holds a queue with a single element. We can say: A. the element is held at index 0. B. the value of front is -1 C. the value of front is one less than the value of rear. D. the value of front is equal to the value of rear.
Computer Science CODE IN C++: You have to design and implement a game in which the avatar has to find the hidden treasure in circus. Theonly way to guide the avatar and to find the treasure is to find the shortest path that leads to the hiddentreasure. You, being a developer are bound to use the Queue data structure. Among, depth first search andbreath first search, determine the most suitable algorithm and provide a complete code. Decide the suitablename of the avatar and the game since you are the designer. Data should be taken from the user. Makerelevant assumptions if required
*The Question In the Picture Criteria a. Create a class called Queue with member variable queueArr, integer queue array, integer rear, integer front b. i. Initialize rear and front to -1ii. Receive an integer and check if queue is full, if not then insert the integer to the queue arrayiii. Delete front element from queue if front is not equal to rear (empty)iv. Print out the queue array if rear is not equal to front. c. i. Provides a choice to the user if they want to insert, delete or display the queue. ii. According to the user response, the appropriate function is called.
Consider the following code segment , The variable q is an object of type Queue, the variable s is an object of type Stack. peek method looks at the first element in the queue without removing it. the remove method removes the first element from the queue. add method adds an element to the and of the queue or add an element to the top of the stack. pop method removes an element from the top of the stack What would be the content of the variable q (8 numbers) after we complete the second while loop in the code for (int i = 30; i <= 40; i ++) { if(i % 3 == 0) q.add(i); } while (!q.isEmpty()) { s.add(q.peek()); s.add(q.peek()); q.remove(); } while (!s.isEmpty()) { q.add(s.pop()); }
1. Create a class to implement a queue using a circular array. a. The class should contain functions to i. Insert a new value, ii. Delete a value. iii. Change a value equal to X to a value equal to Y. iv. Count all value equal to X in the queue. v. For each function above perform an asymptotic analysis and state the worst case performance of the algorithm.
C++ PROGRAM Data Structures Implement a Priority Queue of names such that alphabetically smaller names are always the first ones to be dequeued. Take five to ten random names from the user and insert them in queue in order. Then call the dequeue function multiple times to obtain alphabetically smaller names from queue and print them.
With the concepts of Queue Data Structure, write the functions performing the following tasks: 1. Insertion of an element in the Queue i.e. enqueue() 2. Deletion of an Element from the Queue i.e. dequeue() 3. Display All Elements in the Queue i.e. dispqueue() 4. Display the Element at the Front i.e. dispfront() 5. enqueue() the Queue with the elements in ascending order. After that, use the above four functions to display the same elements in the Queue in descending order.
Java Algorithm Programming Question Implement the ADT queue by using a circular linked list. Recall that this list has only an external reference to its last note. Example Output: Create a queue: isEmpty () returns true Add to queue to get Joe Jess Jim Jill Jane Jerry isEmpty () returns false Testing getFront and dequeue: Joe is at the front of the queue. Joe is removed from the front of the queue. Jess is at the front of the queue. Jess is removed from the front of the queue. Jim is at the front of the queue. Jim is removed from the front of the queue. Jill is at the front of the queue. Jill is removed from the front of the queue. Jane is at the front of the queue. Jane is removed from the front of the queue. Jerry is at the front of the queue. Jerry is removed from the front of the queue. The queue should be empty: isEmpty() returns true Add to queue to get Joe Jess Jim Testing clear: isEmpty() returns true Add to queue to get Joe Jess Jim Joe is at the front of the queue. Joe is…

solve wih java just choose correct answer
