Create a different Enqueue module for your queue (Exercise 5.29) such that it's now a
priority queue.
A priority queue is a first in, first out queue in every respect except one: Items are not always added at the end of the queue. Instead, items are inserted into a priority queue at a position that is based on their priority: The higher their priority, the closer to the front of the line they get.
