Under what circumstances could the head and tail references for the linked implementation or the front and rear references of the array implementation be equal?

What will be an ideal response?


With a linked implementation, head and tail are equal when the queue is empty and they are both null. They are also equal when there is only one element in the queue.
With a circular array implementation, front and rear are equal when the array is empty or the array is full.
