If the parking lot grew to an arbitrarily large size, there are several changes that would need to be made to the parking lot program:
The data structure used to store information about the parking spaces in the lot would need to be able to handle a large number of spaces. This might involve using a dynamic data structure, such as a linked list or hash table, rather than a fixed-size array.
The algorithm for finding an available parking space would need to be optimized for large lots. This could involve using an indexing scheme or a more efficient search algorithm to quickly locate an open space.
The program would need to handle the case where all spaces are occupied. This might involve adding a waitlist or notification system to alert users when a space becomes available.
The program would need to be able to handle large numbers of users simultaneously. This might involve using a distributed system or implementing concurrency controls to ensure that the program can handle multiple requests at the same time.
The program would need to be tested and debugged thoroughly to ensure that it can handle the larger size and increased usage of the parking lot.
