I want to use a list of strings (in descr) to this function so that each element is placed
at the beginning of each list.
Currently
(listru '("R1" "R2" "R3" "R4" "R5") [3 2 1 1 0]) gives me
(("xxxxx" "xxxxx" "xxxxx")
("xxxxx" "xxxxx" "")
("xxxxx" "" "")
("xxxxx" "" "")
("" "" ""))
I want to get the following
(("R1" "xxxxx" "xxxxx" "xxxxx")
("R2" "xxxxx" "xxxxx" "")
("R3" "xxxxx" "" "")
("R4" "xxxxx" "" "")
("R5" "" "" ""))
This is the function
(defun listru (descr rekr)
"DOCSTRING."
(mapcar
(lambda (n)
(append (make-list n "xxxxx")
(make-list (- 3 n) "")))
rekr))
