Q1: Booking System Design - 2024 Real Question

Problem: Design a booking system to handle reservations with availability checks and conflict resolution.

Solution (Java):

class BookingSystem {
    Map<String, List<Booking>> bookings = new HashMap<>();

    public boolean book(String propertyId, LocalDate start, LocalDate end) {
        List<Booking> propertyBookings = bookings.getOrDefault(propertyId, new ArrayList<>());

        // Check for conflicts
        for (Booking booking : propertyBookings) {
            if (isOverlapping(start, end, booking.start, booking.end)) {
                return false; // Conflict found
            }
        }

        // Create new booking
        Booking newBooking = new Booking(propertyId, start, end);
        propertyBookings.add(newBooking);
        bookings.put(propertyId, propertyBookings);
        return true;
    }

    private boolean isOverlapping(LocalDate s1, LocalDate e1, LocalDate s2, LocalDate e2) {
        return s1.isBefore(e2) && s2.isBefore(e1);
    }
}
