Assume you have a queue with a maximum size of 100 elements and you want to perform the following operations: Enqueue 50 elements into the queue. Dequeue 20 elements from the queue. Enqueue 80 elements into the queue. Dequeue 60 elements from the queue. Enqueue 40 elements into the queue. What is the final size of the queue after performing all these operations?
Can you please help me with this code because i am struggling on how to do this, this code has to be in C code.question that i need help with:Priority with round-robin schedules tasks in order of priority and uses round-robin scheduling for tasks with equal priority. There will be multiple queues in the system each representing one priority class. For ease of implementation, you need total 1 through max_priority numbers of queues. You should start scheduling job out of the max priority queue and serve the members of the queue following RR. The schedule of tasks has the form [task name] [priority] [CPU burst], with the following example format: T1, 4, 20 T2, 2, 25 T3, 3, 25 T4, 3, 15 T5, 10, 10 The output should look like this: Running task = [P1] [4] [5] for 5 units. Task P1 finished. Running task = [P5] [3] [4] for 4 units. Task P5 finished. Running task = [P4] [2] [7] for 1 units. Task P4 exhausted its Quantum hence will be Rescheduled. Running task = [P3] [2] [1] for 1 units. Task…

Which best describes this axiom: aList . getEntry ( i + 1 ) = ( aList . remove ( i ) ) . getEntry ( i ) When an item is removed from a list the items below are all moved toward the end of the list to fill the gap When an item is removed from a list the position is held open for the next item that gets inserted When an item is removed from a list the items below are all moved toward the beginning of the list to fill the gap None of these

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.
