I was just wondering that the flood-fill algorithm can be implemented in both recursive or iterative method. Given your explanation, I believe if I try to replace my current iterative approach with the recursive one, it eliminates the need for a queueing container.

It would still be very appreciated if you could explain the best approach to implement the iterative approach which seems to offer better performance while also using less memory.
