Task «Vehicle management system with inheritance and polymorphism»
Develop a class system for managing a fleet of vehicles. Create an abstract class `Vehicle` with fields: `id` (int), `brand` (String), `model` (String), `year` (int) and an abstract method `getInfo()`. Inherit from it the classes `Car` (additional field: `int doors`) and `Motorcycle` (additional field: `boolean hasSidecar`). Implement a `Fleet` class that contains a list of `Vehicle` and methods: `addVehicle(Vehicle v)`, `removeVehicle(int id)`, `getVehicleInfo(int id)` (returns information about the vehicle in the format: "id brand model year doors" for Car and "id brand model year sidecar" for Motorcycle, where sidecar is output as "yes" or "no"), `listAllVehicles()` (outputs information about all vehicles, each on a new line). In `main`, read from stdin the number of commands N, then N commands: "ADD id brand model year type [param]", "REMOVE id", "INFO id", "LIST". For ADD, type can be "Car" (then param = doors) or "Motorcycle" (param = "yes"/"no"). It is guaranteed that ids are unique. Output the results of the INFO and LIST commands.
Input Format
On the first line, an integer N (1 <= N <= 100). Then N lines of commands: ADD id brand model year type param, REMOVE id, INFO id, LIST.
Output Format
For each INFO command, output a line with information about the vehicle. For the LIST command, output information about all vehicles in the order they were added, one line per vehicle. If a vehicle with the specified id is not found for INFO or REMOVE, output "Not found".
