PROGRAMMING:Creation and output of book information table based on sequential storage structure
Define a sequence table containing book information (book number, book name, price), read in the corresponding book data to complete the creation of the book information table, then count the number of books in the book table, and output the information of each book line by line.
###Input format:
Input n + 1 lines, where the first n lines are the information of n books (book number, title and price), each book information occupies one line, and the book number, title and price are separated by spaces, and there is no space after the price. The last line n + 1 is the end of input flag: 0 (three zeros separated by spaces). The book number and title are string type, and the price is floating-point type.
###Output format:
Total N + 1 lines, the first line is the number of books in the created book table, the last N line is the information of n books (book number, book name, price), each book information occupies one line, book number, book name, price are separated by spaces. The price output retains two decimal places.
###Input example:
Here is a set of inputs. For example:
```in
