Parking Lot Simulation

You are required to implement a parking lot simulation system. The parking lot has a fixed capacity and supports the following operations:

• park <vehicle_id>: Park a vehicle with the given id. Return True if the parking is successful and False if the parking lot is full.
• leave <vehicle_id>: Remove the vehicle with the given id from the parking lot. Return True if the vehicle was present and removed, otherwise return False.
• status: Print the current status of the parking lot. If there are parked vehicles, output a space separated list of sentences of the format: Vehicle X is parked. for each vehicle (in the order they were parked). If no vehicles are parked, output Parking lot is empty.
• getFreeSlots: Output the number of free slots remaining in the parking lot.

The system will process a series of operations given via standard input and produce the corresponding outputs to standard output.

Formally, let \( C \) be the capacity of the parking lot. For each operation, perform the action and print the result immediately. For a park or leave operation, print True or False as the result. For a status operation, output the status string and for a getFreeSlots operation, output a number.

Note: The order in which the vehicles are parked should be preserved in the status output.

inputFormat

The first line of input contains an integer \( C \), the capacity of the parking lot. The second line contains an integer \( N \), the number of operations to perform. The following \( N \) lines each contain an operation in one of the four formats:

• park <vehicle_id>
• leave <vehicle_id>
• status
• getFreeSlots

outputFormat

For each operation, output the result to standard output on a separate line:

• For park and leave operations, output True or False.
• For status, output the current status string. If there are parked vehicles, output a space separated series of phrases of the form Vehicle X is parked. for each parked vehicle; otherwise, output Parking lot is empty..
• For getFreeSlots, output the number of available slots.
