Implement a function that, given a list of tennis court bookings with start and finish times, returns a plan assigning each booking to a specific court, ensuring each court is used by only one booking at a time and using the minimum number of courts. An unlimited number of courts are available. After each booking, a fixed amount of time, X, is needed to maintain the court before it can be rented again. Maintenance is required only after X amount of usage.
