Appendix A notes

In other programming languages, such as Scheme, the Hello World program is usually not your first program. In Scheme you often start with a program like this:

(define (factorial n) (if (= n 0) 1 (* n (factorial (- n 1)))))

This computes the factorial of a number; that is, running (factorial 5) would output 120, which is computed by doing 5 * 4 * 3 * 2 * 1 * 1.
