Recursion in Scheme
By Maurice Ticas
As promised from the "Update" Febuary 6th post, we can now recur to produce the total number of triangles inside the \(n^{th}\) iteration of the Sierpinski triangle using the code below written in Scheme.
1 2 3 4 5 | (define sierpinski
(lambda (n)
(cond
((zero? n) 1)
(else (+ 1 (* 3 (sierpinski(- n 1))))))))

To do the recursion on your computer, install mit-scheme, then copy and paste the code to your mit-scheme implementation. You then will be able to call the function for any desirable \(n\). Now go ahead and recur!
