Book Section Classification

You are given the content of a book as an input string. Your task is to classify the book into one of three sections based on its content:

• Fiction: output 1
• Non-Fiction: output 2
• Reference: output 3

The classification is determined by detecting key phrases in the text. For example, a book with the content Magic of Numbers should be classified as Fiction, one with The Python Guide as Non-Fiction, and one with Python Reference as Reference.

Note: If the input does not match any of the above cases exactly, you may output a default value (for instance, 1).

The input is provided via standard input (stdin) and consists of a single line containing the book content.
