Library Service

In this task, you will enhance a basic library management system in Kotlin by implementing several functions in the LibraryService class.

This system allows users to add books to their libraries and search for them by title, author, or genre. The LibraryService class already contains skeleton methods you must fill out.

Additionally, you are provided with two data classes: Book and Author.

• A Book contains a title, list of authors, publication date, genre, and ISBN fields.
• An Author data class has only one field, name.

Instructions

1. Create an Author class with a single field name of type String.

2. Create a Book class with the fields described below. Please put them in the order as follows:

   • title of type String;

   • authors of type List<Author>;

   • publicationYear of type Int;

   • genre of type String;

   • isbn of type String;

3. Implement the addBook(book: Book) method to add a new book to the library.

💡Use some collection here. Book duplicates are allowed.

4. Implement the searchByTitle(title: String): List<Book> method to return a list of books that contain the given title. The search should be case-insensitive.

5. Implement the searchByAuthor(authorName: String): List<Book> method to return a list of books written by authors whose names contain the given string. This search should also be case-insensitive.

6. Implement the searchByGenre(genre: String): List<Book> method to return a list of books that match the given genre exactly, with case-insensitivity.
