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)))

I am planning on going through the questions and rewording them so that the argument order is different. Often the lisp solution has the reverse order as a standard Haskell solution. It seems like asking for the more curry friendly solution would teach good coding style.

If you think you have a reasonable objection let me know.<br>

Also I think it would be beneficial to change the example answers so that the functions that index lists naturally start at 0.<br>
