5. [8 points] Another linked-list implementation of queues is to use a dummy cell. A dummy cel is an empty cell h i he first position of the queue. If the queue is empty then front and rear point to the dummy cell. Implement the queue operations for this representation. How does this implementation compare with the list implementation given i ca of edruoces tiiatin class in terms of speed (running time) and space utilization? 5.
