Library Management System

This problem requires you to implement a simple library management system which can store and retrieve information about books and journals. You are required to design three classes:

• Book: Stores a book's title, author, and ISBN.
• Journal: Inherits from Book and includes an additional field for the issue number.
• Library: Manages a collection of books and journals with the ability to add new entries and retrieve the list of stored information.

For a given sequence of commands issued through standard input, your program should update the library accordingly and output the complete list of book/journal information when requested. Note that titles and authors provided in the input may use underscores ('_') in place of spaces. Your program should replace these underscores with spaces in the output.

The format for the output of each book is given by the following formulas:

• Book: \(Title: {title}, Author: {author}, ISBN: {isbn}\)
• Journal: \(Title: {title}, Author: {author}, ISBN: {isbn}, Issue Number: {issue_number}\)

inputFormat

The input is provided through standard input. The first line contains an integer N, representing the number of commands. The following N lines each contain a command. There are three types of commands:

1. ADD_BOOK title author isbn
   • Add a book with the given title, author, and ISBN.
2. ADD_JOURNAL title author isbn issue_number
   • Add a journal with the given title, author, ISBN, and issue number (an integer).
3. PRINT_LIBRARY
   • Print the information of all books in the library in the order they were added. Note: Titles and authors may have underscores (_) instead of spaces.

outputFormat

For each PRINT_LIBRARY command, print the information of each book/journal stored in the library on a new line. The output for each item should follow the format:

• For a Book: "Title: {title}, Author: {author}, ISBN: {isbn}"
• For a Journal: "Title: {title}, Author: {author}, ISBN: {isbn}, Issue Number: {issue_number}"## sample
