Design and implement a RandomQueue. This is an implementation of the Queue interface in which the remove() operation removes an element that is chosen uniformly at random among all the elements currently in the queue. (Think of a RandomQueue as a bag in which we can add elements or reach in and blindly remove some random element.) The add(x) and remove() operations in a RandomQueue should run in constant time per operation.

In a bank, customers wait in a queue (q0) for their turn to complete a transaction. Customers who come first are served first. At a certain point when there are lots of customers waiting, a decision is taken to split the queue elements into two empty queues q1 and q2. The customers are split based on the alphabetical order of their first names. Customers with first name starting A-H are added to q1 while the others (first name starting I-Z) are added to q2. In an application, write a method named splitQueue (in an application) that accepts as parameters 3 queues, the original queue (q0) and two empty queues (q1 and q2) to be filled as described above. Write also a main method in which you read the first names of customers from the user, fill them into q0 and call the method splitQueue to split q0 elements into q1 and q2. After the split display the elements of q1 first then those of q2. The header of the method is: public static void splitQueue ( Queue q0, Queue q1, Queue q2) Note:…

Write a program for the implementation of a queue using singly linked list. The elements of the queue should be strings of length at most 20 characters. Print the queue and do the following operations on the created queue : (a) Insert a new element. (b) Delete an element from the queue.
A(n) array can be used in an array implementation of a queue to avoid an overflow error at the rear of the queue when the queue is not full.

The bounded-buffer solution in the below code uses a last-in-first-out strategy (LIFO).Change the code to implement a FIFO (First-in-First-out) strategy. You may use the (in,out) pointer method(using semaphores to test if the queue is full or empty shouldalleviate the problem of only using up N-1 locations) or implement a FIFO queue.

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?
C/C++ Using linked lists implement an amusement park reservation system. The system allows a person to make a reservation for a specific date. A person can change the reservation date or even cancel his booking anytime. The system puts all reservations in a queue. The park will allow only certain number of persons on any given day in order the reservation was made. For each day the system will print out persons allowed to visit the park. For sake of simplicity, dates are being confined to 15th to 30th. The system should ask the user to enter code for different operations. It reads all data from the datafile amusement.dat. The first integer on datafile indicates limit of persons allowed on any day. i)code 1: make reservation, system expects date followed by name (within 20 characters) and makes reservation. If number of bookings exceeds allowed number, then system prints SORRY, QUOTA OVER and moves over to read next code. ii)code 2: change date of reservation, system expects old date,…
1. Suppose you have a circular queue of size 6 (1 to 6). Initially the value of thefront and rear is 0. Now show the state of the queue if the following operationis performed on the queue. Also find the value of front and rear in each step.insert (10); insert (5), delete (), insert (9); insert (9); insert (7); insert (5); insert(8); insert (10); insert (11).
Given a singly linked list, print reverse of it using a recursive function printLinkedList( node *first ) where first is the pointer pointing to the first data node. For example, if the given linked list is 1->2->3->4, then output should be: 4 3 2 1 (note the whitespace in between each data value)
