:I do not know enough about Newlisp to be very helpful, but I formatted your code to better represent matching parenthesis. (I am stuck on: How does L work in the function position of a list when composing arguments for nested stoogesorts? Also, what modifies the L which you return from your defined function?) --[[User:Rdm|Rdm]] 15:19, 5 August 2010 (UTC)

Revision as of 15:19, 5 August 2010
Im having a bit of an issue with syntax apparently. I have the latest code here: <lang Newlisp>
(define (stoogesort L left right)
(println "list : " L " left: " left " right: " right " calc: " (- right (/ (- right (+ left 1))3))) (if (> ( L left ) ( L right )) (swap (L left) (L right) (if (< (- left right) 1) (print "hello") (stoogesort (L left (- right (/ (- right (+ left 1))3)) (stoogesort (L (+ left (/ (- right (+ left 1))3)) right (stoogesort(L left (- right (/ (- right (+ left 1))3))))))))))) L)
(stoogesort (list 7 3 2 3 4 0) 0 5)
</lang> It seems to never get to the recursive step. I'm wondering why as I did some other tests to see whats going on. I feel extremely dumb right now with such an algorithm.... --Michael Chrisco
