Problem: Create a library management system using a linked list that can perform the

following operations:

$-$ Insert book record

$-$ Delete book record

$-$ Update book record

$-$ Show details of a book

$-$ Search for a book

Book Record Details:

$-$ Title of the Book

$-$ Author of the Book

$-$ ISBN $($International Standard Book Number$)$

$-$ Genre

$-$ Number of Copies Available

$-$ Shelf Number

Approach:

$1.$ Insert book record: Create a new node with book details and insert it into the

linked list.

$2.$ Delete Record: Delete Record is similar to deleting a key from a linked list. Here the key is the ISBN number. Delete record is an integer returning function it returns $-1$ if no such record with a given roll number is found otherwise it deletes the node with the given key and returns $0.$

$3.$ Update book record: To update relevant fields of the book's node, such as author, genre, or number of copies.

$4.$ Show details of a book: Display all elements of the linked list by showing the record, similar to printing all elements of the linked list.

$5.$ Search Record: Search a Record is similar to searching for a key in the linked list; in this case, the book record's key is the unique ISBN number for every book.

Recommendations:

$1.$ Using ISBN as a key: Ensure that ISBN is used as a unique identifier for each book to prevent duplicates.

$2.$ Inserting records in sorted order: Implement a method to insert new books in sorted order based on ISBN or title. This will make searching and updating records more eUicient.
