Write a program to read data from a hotel reservation (room number, date check-in and check-out date) and show booking details, including its duration in days. Then read new arrival and departure dates, update the reservation, and show rebooking with the updated data. The program must not accept data invalid for the reservation, according to the following rules:
- Booking changes can only occur for future dates
- The check-out date must be greater than the check-in date testing
