Mobile App Development Problem: Build an iOS application that implements the Aircraft queue shown below. Your mobile app should provide and interface to allow the user to: - Initialize the queue - Add a new aircraft to the queue. - Retrieve the next aircraft from the queue. Aircraft Queue A software subsystem of an air-traffic control system is defined to manage a queue of aircraft (AC) in an airport. The aircraft queue is managed by a process which responds to three types of requests: - system boot used to start the system. - enqueue aircraft used to insert a new AC into the system. - dequeue aircraft used to remove an AC from the system. AC’s have the following properties: - AC type: Passenger or Cargo - AC size: Small or Large The process which manages the queue of AC’s satisfies the following: - There is no limit on the number of AC’s it can manage (could be tens of thousands) - Dequeue aircraft requests result in selection of one AC for removal such that: - Passenger AC’s have removal precedence over Cargo AC’s - Large AC’s of a given type have removal precedence over Small AC’s of the same type. - Earlier enqueued AC’s of a given type and size have precedence over later enqueued AC’s of the same type and size.
