- An array of size MAX_SIZE is used to implement a queue. head, tail, and size are tracked. Suppose front is 0 and rear is MAX_SIZE -1. How many elements are present in the queue? a. 0 b. MAX_SIZE-1 c. MAX_SIZE d. 1Create a class called ResizingArrayQueueOfStrings that implements the queue abstraction using a fixed-size array. Then, as an extension, utilise array resizing in your implementation to get rid of the size constraint.If the following is a circular array based queue of size 99 43 54 76 93 77 18 If rear is at index 1 and front is at index 6, what is the size of the queue?

- In Javascript an array can be treated like a queue---a FIFO (first-in, first-out) data structure. Which two array operations that we studied in class can be used together to treat an array as a queue? a. isEmpty() and isFull() b. queue() and unqueue() c. unshift() and pop() d. push() and pop() e. unshift() and shift()Given a Queue of Integers with the interface: public void enqueue(Integer i) // add to endpublic Integer dequeue() // remove from frontpublic boolean isEmpty() // return true if empty Write a method rearrange(Queue q) that takes a queue of integers as a parameter and rearranges the order of the values so that all of the odd values appear before the even values and that otherwise preserves the original order of the list. For example, if a Queue contained [3, 5, 4, 17, 6, 83, 1, 84, 16, 37] after call rearrange it would contain [ 3, 5, 17, 83, 1, 37, 4, 6, 84, 16] You may use any internal data structures you chose. Hint: I recommend even and odd queues in your method.A) Write a generic Java queue class (a plain queue, not a priority queue). Then, call it GenericQueue, because the JDK already has an interface called Queue. This class must be able to create a queue of objects of any reference type. Consider the GenericStack class shown below for some hints. Like the Stack class below, the GenericQueue should use an underlying ArrayList<E>. Write these methods and any others you find useful: enqueue() adds an E to the queue peek() returns a reference to the object that has been in the queue the longest, without removing it from the queue dequeue() returns the E that has been in the queue the longest, and removes it from the queue contains(T t) returns true if the queue contains at least one object that is equal to t *in the sense that calling .equals() on the object with t the parameter returns true.* Otherwise contains returns false. size() and isEmpty() are obvious.

For some reason, queues can only be implemented using a circular array.Create a simple java program with a linked list that will hold 5 nodes (names of your teacher in the CICS this semester including me, V. Agcaoili). In the program, show how to add nodes by adding a name of faculty from other College as the third element in the linked list. Show also how to access the node(name) V.Agcaoili. Also, show how to change/update nodes by changing the element V.Agcaoili into V.Sinco. Finally, show how to remove nodes by removing the name of the faculty who is not from the CICS Department.
