In 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.
b. Write out the order of elements that are contained in a queue after the following operations are performed. myQueue.enqueue(new Integer(16)); myQueue.enqueue(new Integer(12)); Integer num1 = myQueue.dequeue(); myQueue.enqueue(new Integer(6)); myQueue.enqueue(new Integer(8)); myQueue.enqueue(new Integer(30)); myQueue.enqueue(new Integer(24)); myQueue.enqueue(new Integer(18)); myQueue.dequeue(); myQueue.dequeue(); myQueue.dequeue(); myQueue.enqueue(new Integer(38); Show how step by step process of arriving at your answer.
in c++ Write a function that takes a queue with 20 integer values and deletes the elements thatare between 15 and 20. In other words, only the elements less than 15 or greater than 20remain in the queue. This means that you need to have an auxiliary queue to store theelements between 15 and 20 and restore them back to the original queue.

*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.

JAVA 1-Write an application using a hash table that finds all the pairs of two integers within the below array that add up to 12.Array = {4,9,6,13,5,3,2,8} 2-Develop an application that stores characters A, B and C in a queue array and then displays both the size and the first-in element of the stack. The application should then remove the first element of the queue and then display both the size and the first-in element of the queue again. Appropriate queue methods should be used to add, delete and display characters. 3-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. 4-Write a program that merges two ordered-list objects of integers into a single ordered list object of…
