We have been contracted to write a software subsystem for an air traffic control
system. This software manages a queue of aircrafts and prioritizes the orders of
take offs and landings based on the aircraft's type and size. Write a
constructor function, ATCQueue
, that creates and manages the aircraft queue.
Aircrafts are represented by objects that have at least, but are not limited to, the following properties.
Property | Value |
---|---|
type |
passenger or cargo |
size |
small or large |
The aircraft queue should implement the following interface.
Method | Parameters | Return | Notes |
---|---|---|---|
aircraftCount() |
None | Integer | Count the number of aircrafts in the queue. |
enqueue() |
Aircraft | None | Add an aircraft to the queue. |
dequeue() |
None | Aircraft | Remove an aircraft from the queue and return it. |
The process that manages the aircraft queue satisfies the following conditions.
- There is no limit on the size of the aircraft queue.
- Aircrafts are dequeued according to their priority.
- Passenger aircrafts have higher priority than cargo aircrafts.
- If two aircrafts have the same type but different sizes, then the large aircraft has a higher priority.
- If there is more than one aircraft with the same type and size, then the aircraft that was enqueued earlier has higher priority.
You should be running grunt nag
before diagnosing any bugs, since it finds
some of the most common sources of errors. After grunt nag
passes, you should
run grunt test
to run the included tests. Tests will tell you whether of not
you've met these requirements.
Developers should run these often!
grunt nag
or justgrunt
: runs code quality analysis tools on your code and complains.grunt reformat
: reformats all your code in a standard style.grunt test
: runs any automated tests; may depend ongrunt build
