4 cards from this section. Quick, good the night before a test.
What is a priority queue?
Think about how tasks are managed in an operating system.
What is the time complexity for inserting a task in an unsorted list?
Consider how you would append an item to a list.
What operation is performed to remove the highest priority item from a priority queue?
Remember the two primary operations of a priority queue.
True or False: An unsorted list allows for faster retrieval of the maximum priority item compared to a sorted list.
Think about how the items in each list are organized.
Construct a priority queue using a two-dimensional array, and perform a series of inserts and deletes. Provide a computational analysis of the operations.
Track operations clearly with comments in your code for analysis.
Evaluate which priority queue structure (unsorted, sorted, or heap) would be optimal for a system processing 1000 jobs with varied priority levels. Justify your answer.
Consider not only time complexity but also real-world factors like memory overhead.
