Consider an airport management system. Each airport has a unique id (e.g. Montreal:YUL). Let us introduce the types AIRPORT and CITY . We also introduce variable airports that contains associations between airport id’s and their corresponding host cities. A possible state of the system is shown below:airports ={YUL → Montreal,LCY → London_UKLHR → London_UK,MIL → Milan,SFO → San_Francisco,SDQ → Santo_Domingo}1. (PROGRAMMING) Define global variable airports in Common LISP and populate it with the above data. Demonstrate that the variable indeed contains the ordered pairs as shown above.2. Provide a declaration of variable monitored that holds all airport id’s.3. What kind of variable is airports? Provide a formal definition together with any and all applicable properties.4. Describe what data structure you would deploy to model variable airports. Note that you may not use a Dictionary. Should this be an ordered or an unordered structure? Discuss.5. Provide a formal specification of the state of the system in terms of a Z specification schema.6. Provide a schema for operation AddAirportOK that adds a new airport to the system. With the aid of success and error schema(s), provide a definition for operation AddAirport that the system will place in its exposed interface. 7.(PROGRAMMING) Define function AddAirport in Common LISP.8. Provide a schema for operation UpdateAirportOK that updates the host city of a given airport. With the aid of success and error schema(s), provide a definition for operation UpdateAirport that the system will place in its exposed interface.9. What would be the value of variable airports upon calling UpdateAirport(YUL, Dorval)?10. (PROGRAMMING) Define function UpdateAirport in Common LISP.11. Provide a schema for operation DeleteAirportOK that removes an airport from the system. With the aid of success and error schema(s), provide a definition for operation DeleteAirport that the system will place in its exposed interface.12. (PROGRAMMING) Define function DeleteAirport in Common LISP.13. Provide a schema for operation GetAllAirportsOK that returns all airports hosted by a given city. With the aid of success and error schema(s), provide a definition for operation GetAllAirports that the system will place in its exposed interface.14. (PROGRAMMING) Define function GetAllAirports in Common LISP. (PLEASE ANSWER ALL. ALL OF THESE ARE CONNECTED. PLEASE PLEASE)
