What does "Lisp solution?" mean? Lots of them are listed "Yes", and lots are listed "No", but I can't detect a difference between these entries... -- dmwit
It's just whether or not there's a lisp solution available. If you go to the description of the problem, and click on the problem number, it'll either link you to actual lisp code, or a "not found" page. There are 25 of them which actually have lisp code available. -- chessguy
What is the meaning of that scoreboard? Even though there is no solution on the L-99 site, there may still exist a LISP solution, even a trivial one. And since that L-99 site is no wiki and this site is, the scoreboard seems just misleading to me.
Just an example for Problem 12:
(defun decode-modified (list) (reduce #'append (mapcar (lambda (item) (if (atom item) (list item) (make-list (car item) :initial-element (cadr item)))) list)))
