Overdue Books Detector

You are given the current date and a list of borrowed books with their return dates. A book is considered overdue if its return date is strictly earlier than the current date. Formally, a book with return date \( r \) is overdue if \( r < c \), where \( c \) is the current date provided.

Your task is to print the titles of all overdue books, each on a new line. If no book is overdue, print nothing.

inputFormat

The input is given via stdin in the following format:

<current_date>
<n>
<title_1>,<return_date_1>
<title_2>,<return_date_2>
... 
<title_n>,<return_date_n>

Where:

• <current_date> is a string in the format YYYY-MM-DD.
• <n> is an integer indicating the number of borrowed books.
• Each of the next n lines contains a book's title and its return date (in YYYY-MM-DD format) separated by a comma.

outputFormat

Output the titles of overdue books to stdout, each on a separate line. If there are no overdue books, output nothing.
