Basics of priority queues
Priority queues are queues in which the elements are kept in a sorted order.
Scheduling jobs of relative importance is example where items should be maintained in the queue in order of importance.
Priority queues provide more flexibility than simple searching, because they allow for new elements to enter the system at arbitrary intervals.
The cost-effectiveness of inserting a new job into a queue, instead of constantly sorting and resorting and resorting again.
