Explain why the array implementation of a stack does not require elements to be shifted but the noncircular array implementation of a queue does.
What will be an ideal response?
All operations on a stack occur on one end of the stack (the top). Therefore, the bottom of the stack can remain at location 0 of the array at all times. Operations on a queue, on the other hand, occur at both ends – additions to one end and removals from the other. If a non-circular array is used, the end can "move away" from index 0, requiring a shift in the elements to keep the elements rooted at that location.
