Internal implementations of stacks and queues require the tracking of more information than simply the data being stored in the stack or queue. What is the nature of this information and why does it need to be stored? Does it differ between the objects? If so, how and why does it differ? If not, why can it be the same across object types?

Expert Solution

  • Stack is internally implemented in such a way that the element inserted at the last in stack would be the first element to come out of it.So stack allows LIFO(Last in and First Out).
  • Queue is implemented in such a manner that the element inserted at the first in queue would be the first element to come out of it.So queue follows FIFO(First in and First Out).
  • Adding and removing operations in stack is known as push and pop respectively.
  • Adding and removing operations in queue is known as enqueue and dequeue.
  • In stack only one flag is maintained to access the list which always point to the last element present in the list.
  • In Queue two flags are maintained to access the list.The front flag always points to the first element inserted in the list and is still present,and the rear flag always points to the last inserted element.
  • Stack does not have any varient and not implemented further.
  • Queue has varients like circular queue,priority queue,doubly ended queue.
  • Stack is more simpler than Queue.
  • Both data structure are useful to store the data objects.So it will take almost the same size memory to store the same amount of data elements.
  • Stack needs only one pointer called top-pointer.(It points to the topmost object in the stack)
  • The queue requires two pointers.(One is front and the other is rear pointer).

If you haven't heard of the term "continuous auditing" it is a little more than simply the continuous monitoring of the or a business process/transaction cycle. Continuous auditing will demand the involvement of Accounting Information Service and IT professionals. Let's explore (research) this topic and discuss what it means for us. We'll need some definitions, best practices, critical players, helpful technology (hardware/software, and, of course, specifics) for our role.
