What would be the time complexity of the size operation for each of the implementations if there were not a count variable?
What will be an ideal response?
With the count variable, the size operation is O(1) for all implementations. Without the count variable, the regular array solution and the linked solution would require the current elements to be counted, making the complexity O(n). For the circular array solution, the number of elements could be computed using the front and rear pointers (taking into account whether the end of the array is being spanned), so it would remain O(1).
