Question text Case study: A small online bookstore wants to manage customer orders efficiently. Each customer can select up to three books from the available titles. The system should keep track of the customer names and the list of books they have ordered. The bookstore requires a Python program that can record customer names along with their selected books, ensure that each customer cannot order more than three books, and automatically remove any duplicate books in a customer’s order using a set. The program should also display each customer’s name together with the books they have ordered, and count and display the total number of books ordered by all customers. Sample Output: Alice ordered {'Book A', 'Book B'}Bob ordered {'Book A', 'Book B', 'Book C'}Charlie ordered {'Book C'}Total books ordered: 6 Question: Complete the Python code below by filling in the missing statements in 10 blanks so that the system works as described above.
