- A. Suppose that q1 is a class CircularQueue object that is using circular queue concept and the maximum size of the array implementing q1 is 10. The current index value of front is 5 while the current index value of rear is 9. i. What are the index values of front and rear after adding TWO (2) elements into q1? Draw the circular queue diagram to show the addition process. ii. After implementing the process in Question 2A (i), what are the index values of front and rear after removing FIVE (5) elements from q1? Draw the circular queue diagram to show the removing process. iii. What are the current number of elements after implementing the process in Question 2A (i) and Question 2A (ii)? =======================This is a java data structures question - Given a circular bent array-based queue capable of holding 100 objects. Suppose the queue is initially empty, and then objects are put into the queue at the rate of 10 per minute while meantime they are processed and removed from the queue at the rate of 5 per minute. After 120 elements have been added to the queue, which of the following is true? CIRCLE JUST ONE LETTER FOR THE ANSWER. -> You can’t add 120 elements to an array holding 100 entries. -> There will be 60 elements in the queue, 20 of them at the front of the array where the queue started, and 40 at the other end. -> There will be 60 elements in the queue, 30 of them at the front of the array where the queue started, and 30 at the other end. -> There will be 60 elements in the queue, 40 of them at the front of the array where the queue started, and 20 at the other end.illustrate the queue content after every operation in each of the following sequences.

Can a binary search algorithm be written by recursion?Write a complete Program in Java to implement circular queue using array for the following tasks: 1. Method to insert the new element in the circular queue 2. Method to delete an element from the circular queue 3. Method to display all the elements of the circular queue 4. Create the test class to perform the operations on circular queue in the following sequence: a. Add a new element 10 b. Add a new element 20 c. Add a new element 30 d. Add a new element 40 e. Display all elements f. Delete from the circular queue g. Delete from the circular queue h. Add a new element 50 i. Add a new element 60 j. Add a new element 70 Please screenshot of the outputIn 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.
- Write a C++ program for the following question: Given a queue of integers, rearrange the elements by interleaving the first half of the list with the second half of the list. For example, suppose a queue stores the following sequence of values: [11, 12, 13, 14, 15, 16, 17, 18, 19, 20]. Consider the two halves of this list: first half: [11, 12, 13, 14, 15] second half: [16, 17, 18, 19, 20]. These are combined in an alternating fashion to form a sequence of interleave pairs: the first values from each half (11 and 16), then the second values from each half (12 and 17), then the third values from each half (13 and 18), and so on. In each pair, the value from the first half appears before the value from the second half. Thus, after the call, the queue stores the following values: [11, 16, 12, 17, 13, 18, 14, 19, 15, 20].Implement a double-ended queue. It is a variation where enqueues and dequeues are allowed on both ends. Implement the following double-ended queue operations using circular array representation with variables for the front and rear indices: a. new b. clear c. enqueueFront d. enqueueRear e. dequeueFront f. dequeueRear g. isEmpty h. isFull i. peekThis is a java question Given an efficient circular bent array-based queue q capable of holding 7 objects.
