: I sort of expected that, that's why I left the Amazon link alone. For the specific task, the book authors' page has a link to Amazon, while it's hard to go from Amazon to that page. Most users interested in that task probably only need some context instead of the whole book, so a way to read a single chapter should be useful. --[[User:Ledrug|Ledrug]] 04:26, 24 December 2011 (UTC)
== Lisp in the style of the C++ generator ==
Please leave [http://rosettacode.org/wiki/Kaprekar_numbers#In_the_style_of_the_C.2B.2B_generator this code] alone until you can demonstrate an understanding of this problem. Your second attempt at this is an improvement over your first naive attempt, but still not as interesting as [http://rosettacode.org/wiki/Kaprekar_numbers#In_the_style_of_the_C.2B.2B_generator this]. Maybe I shall seperate the [http://rosettacode.org/wiki/Casting_out_nines Casting_out_nines] from the Kaprecar part: <lang clisp>(let ((kk (* N N))) (do ((B Base (* B Base))) ()(let (( nr (/ (* N (- B N)) (- B 1)))) (if (< 0 nr) (let ((q (floor (- N nr)))) (if (= kk (+ nr (* q B)))</lang>
