There N rooms in a hotel so customers will check-in and check-out a rooms simultaneously so which type of data structure you implement and it should be efficient and extension of this prebooking will also happen like say a customer has booked a room 1 month before the check-in date so at that time the room should be available so what type algorithm you use?

Question

Accepted Answer

To efficiently manage room bookings and prebookings in a hotel, a priority queue data structure can be implemented.

A priority queue can be used to prioritize room bookings based on check-in dates.
When a customer checks out, the room becomes available and can be assigned to the next customer in the priority queue.
Prebookings can be stored separately and checked against the availability of rooms before assigning them to customers.
The priority queue can be implemented using a binary heap or a balanced binary search tree for efficient operations.
