Library System Management

You are required to implement a library system management program that processes operations related to borrowing, returning, and listing borrowed books. The system maintains records of books, authors, and members. Each member has an associated list of borrowed books. The operations are as follows:

• borrow: Add a book to the member's borrowed list if no other member has borrowed that same book. Formally, if the book's ISBN, denoted by \(isbn\), is not present in any member's borrowed books (i.e. \(isbn \notin \bigcup_{m \in Members} m.borrowed\_books\)), the operation is allowed.
• return: Remove the book (if present) from the member's borrowed books.
• list: List all books currently borrowed by the specified member.

The program should accept input from stdin and print the result to stdout. For borrow and return operations, print "Success" upon completion. For the list operation, output the list of ISBNs separated by a space. If the member has no borrowed books, output "None".

inputFormat

The input is read from stdin and has the following format:

B
book_line_1
book_line_2
...
book_line_B
A
author_line_1
author_line_2
... 
author_line_A
M
member_line_1
member_line_2
... 
member_line_M
operation
member_id
[isbn]

Explanation:

• B: Number of books.
• Each book_line is in the format: isbn|title|author_id|category.
• A: Number of authors.
• Each author_line is in the format: author_id|name.
• M: Number of members.
• Each member_line is in the format: member_id|name|borrowed_books. If the member does not have any borrowed books, the field will be None; otherwise, multiple ISBNs are separated by a comma.
• operation: One of borrow, return, or list.
• member_id: The member performing the operation.
• If operation is borrow or return, an additional line with isbn is provided.

outputFormat

The output is printed to stdout:

• If the operation is borrow or return, print "Success".
• If the operation is list, print the list of borrowed ISBNs separated by a space. If the list is empty, print "None".
