Why don't we need a circular array implementation of a stack? What quality, specifically, does a queue have that led to a need for the circular array implementation

There is a data structure called a drop-out stack that behaveslike a stack in every respect except that if the stack size is n,then when the n+1 element is pushed, the first element is lost.Implement a drop-out stack using links.

Question 3 a. "Queues and stacks are used in many real-life situations". In your own words, clearly distinguish between queues and stacks; and give one example of real-life situations in which each of them is used. b. In an array-based implementation of a stack, which end of the contents of the array represent the bottom of the stack and why? c. If the size of circular queue K is 4 with indices number from 0 to 3 what would be the state of the queue after the following set of 8 operations below. Show in a diagram the state of queue K after each of the 8 operations. K. enqueue (“F"), K. enqueue (“R"), K. dequeue(), K. enqueue (“P"), dequeue(), K.front(), K. enqueue (“Z"), K. enqueue (“G") d. Why are insertions and deletions at the logical end of the array more efficient than insertions and deletions in the interior of the array?
