Chapter 8, Problem 24CRP
Program Plan Intro
Queue:
Queue is an abstract data structure, which follows the FIFO (First In First Out) method and it is different from stacks and is open at both ends. Data is inserted at one end and is removed from the other end.

5. Suppose the entries in a queue require one memory cell each. The head pointer contains
value 11, and tail pointer contains the value 17. What are the values of these pointers after
one entry is inserted and two are removed?
Consider a variant of the RR scheduling algorithm where the
entries in the ready queue are pointers to the PCBs.
a. What would be the effect of putting two pointers to the
same process in the ready queue?
b. What would be the major advantages and disadvantages
of this scheme?
c. How would you modify the basic RR algorithm to achieve
the same effect without the duplicate pointers?
What is the key difference between a stack and a queue when it comes to data structures, and under what circumstances would one be preferable to the other when it comes to the implementation of algorithms or the resolution of computing problems?

- How does a Circular Queue data structure work, and what are its advantages and disadvantages compared to a regular Queue?arrow_forwardProblem 1 Consider an array-based queue implementation. Suppose we wish to use an extra bitin queue records to indicate whether a queue is empty.1. Modify the declarations and operations for a circular queue to accommodate this feature.2. Would you expect the change to be worthwhile? Problem 2 Given the following specification of a front operation for queue:ItemType FrontFunction: Returns a copy of the front item on the queue.Precondition: Queue is not empty.Postcondition: Queue is not changed.1. Write this operation as client code, using operations from the QueType class. (Remember,the client code has no access to the private variables of the class).2. Write this function as a new member function of the QueType class. Problem 3 Implement the following specification for a Boolean function in the client programthat returns true if two queues are identical and false otherwise.Boolean Identical(QueType queue1, QueType queue2)Function: Determines if two queues are identical.Precondition:…arrow_forwardA priority queue is a queue where a numeric priority is associated with each element. Access to elements that have been inserted into the queue is limited to inspection and removal of the elements with smallest and largest priority only. A priority queue may have multiple items that are of equal priority. Give the ADT specification for a bounded priority queue using the specification method described in Topic 7 of the lecture notes. By "bounded", it is meant that the priority queue has a maximum capacity specified when it is created, and it can never contain more than that number of items. Your specification must specify the following operations: Page 3 newPriorityQueue: make a new queue insert: inserts an element with a certain priority isEmpty: test if the queue is empty isFull: test if the queue is full maxItem: obtain the item in the queue with the highest priority minItem: obtain the item in the queue with the lowest priority deleteMax: remove from the queue the item with the…arrow_forward
- When are examinations of queue processes recommended to be carried out?arrow_forwardWhat is the difference between a stack and a queue data structure, and in what situations would each be the most appropriate choice for implementing algorithms or solving computational problems?arrow_forwardCite 2 real-life examples of each type of queue: i) Queues with non-preemptive priorities; ii) Queues with non-preemptive priorities with limited capacity; iii) Queues with non-preemptive priorities with a finite requesting population; iv) Queues with preemptive prioritiesarrow_forward
- Study the scenario and complete the question(s) that follow: A stack is a collection of objects that are inserted and removed according to the last-in, first-out (LIFO) principle while a queue is a collection of objects that are inserted and removed according to the first-in, first-out (FIFO) principle. A typical example of a stack may include an internet web browsers store the addresses of recently visited sites on a stack. Each time a user visits a new site, that site's address is "pushed" onto the stack of addresses. The browser then allows the user to "pop" back to previously visited sites using the "back" button. 3.1 Develop an application that store characters A, B and C in a stack array and then displays both the size and the last-in element of the stack. The application should then remove the last element of the stack and then display again both the size and the last-in element of the stack. Appropriate stack methods should be used to add, delete and display characters.arrow_forwardProblem 1: Consider an array-based queue implementation. Suppose we wish to use an extra bitin queue records to indicate whether a queue is empty.1. Modify the declarations and operations for a circular queue to accommodate this feature.2. Would you expect the change to be worthwhile?Problem 2: Consider an array-based queue implementation. A variant of the circular queuerecords the position of the front element and the length of the queue.1. Is it necessary in this implementation to limit the length of a queue to maxlength - 1?2. Write the five queue operations for this implementation.3. Compare this implementation with the circular queue implementation discussed in class.Problem 3: A dequeue (double-ended queue) is a list from which elements can be inserted ordeleted at either end.1. Develop an array-based implementation for dequeue.2. Develop a pointer-based implementation for dequeue.arrow_forwardSome have stated that linked Stacks are much better than arrays; others said that Queues are mostly used than arrays are. If that is always valid, then why are arrays used at all? As a conclusion of what you have learnt about them, you are asked to compare Arrays with Stacks and Queues in terms of some areas. The below table includes 4 questions to be answered comparing between the three data structures. You are asked to complete this table with the proper answer, based on your knowledge and your research, and using your own words Case QUEUES ARRAYS STACKS Which principle is used? FIFO-LIFO- INDEXED, with a brief explanation. How do deletion/insertion take place? Dynamic or fixed size? For which problems they are the Best to use?arrow_forward
