Product Availability Search

You run an online store that sells various products. Each product has a unique ID and they are stored in a sorted list. Given a list of product IDs and a product ID to check, determine if the product is in stock. Return 'Available' if it is; otherwise, return 'Not Available'. Input format: - The first line contains an integer n, the number of products. - The second line contains n sorted integers (the product IDs). - The third line contains the integer k, the product ID to check. Output format: - Print 'Available' or 'Not Available'. Example: Input: 5 1 3 5 7 9 5 Output: Available
