Note : addqueue works like Enqueue and deleteQueue works like Dequeue Consider the following statements: (8, 9) queueType queue; int num; Show what is output by the following segment of code num = 7; queue.addQueue (6); queue.addQueue (num); queue.front (); queue.deleteQueue (); queue.addQueue (num + 5); queue.addQueue (14); 2) ; num = queue.addQueue (num queue.addQueue (25); queue.deleteQueue () ; cout « "Queue elements: "; while (!queue.isEmptyQueue ()) { cout <« queue.front () << " "; queue.deleteQueue(); } cout <« endl; Queue elements: 14 14 4 25 Queue elements: 11 14 44 Queue elements: 11 14 4 25 Queue elements: 11 14 25 25

When an element is removed from a queue, where is it removed from?

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.

20 T OR F An application programmer can prevent accessing an empty queue by using the isEmpty method in an if-statement to prevent such access.

how does the structure if counting semaphore primitives differ frim binary semaphore primitives?

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.

Java data struc

What are the chief differences between these three data structures? How can you determine when it is appropriate to use a queue, a dequeue, or a priority queue?

Stack: Stacks are a type of container with LIFO (Last In First Out) type of working, where a new element is added at one end and (top) an element is removed from that end only. Your Stack should not be of the fixed sized. It should be able to grow itself. bool empty() : Returns whether the Stack is empty or not. Time Complexity should be: O(1) bool full() : Returns whether the Stack is full or not. Time Complexity should be: O(1)int size() : Returns the current size of the Stack. Time Complexity should be: O(1)Type top () : Returns the last element of the Stack. Time Complexity should be: O(1) void push(Type) : Adds the element of type Type at the top of the stack. Time Complexity    should be: O(1) Type pop() : Deletes the top most element of the stack and returns it. Time Complexity    should be: O(1) Write non-parameterized constructor for the above class. Write Copy constructor for the above class. Write Destructor for the above class. Now write a global function show stack which…
