Library Archive Search

You need to find if a book with a specific ISBN number exists in a library archive. The library's ISBN list is sorted in ascending order. If the ISBN exists, return 'Exists'; otherwise, return 'Does not exist'. Input: The first line contains an integer n (1 <= n <= 1000), the number of books. The next n lines contain the ISBN numbers as strings (digits only). The last line contains the ISBN to search for. Output: Print 'Exists' or 'Does not exist'. Example: Input: 5 000111222 000222333 000333444 000444555 000555666 000222333 Output: Exists
