Today's book club

[reborgml]

Hello SICP-ers

we could meet today as usual, 12:30-13:30, to discuss last assignments and exercises. If we are a small group (that happened last time) we could also go for some wild TDD hacking on top of 1.18-1.19 with our favourite language. This time ADA LOVELACE! No kitchen.

Cheers

Renzo

Here's Renzo and my stab at 1.17 from today

(define (double n) (* 2 n))
(define (halve n) (/ n 2))

(define (prod a b)
(if (= b 1) 0
(+ (double a) (prod a (halve b)))
)
