A Recursive LISP function which appends two lists together.


Programs in lisp with output

Define a Recursive LISP function which appends two lists together.

SOFTWARE USED:  LispWorks 6.1
THEORY:-
Assuming this is about Common Lisp, there is a function which appends two lists. If you use this function which applies a given function two list as parameters, returns first list with the element of the second list appended.

SOURCE CODE ( IF INCLUDED )
(defun list-append (L1 L2)
  "Append L1 by L2."
  (if (null L1)
      L2
    (cons (first L1) (list-append (rest L1) L2))))
LIST-APPEND
> (list-append '(a  b c) '( c d e))
(A B C C D E)
> (list-append '(4 2)'(2 3))
(4 2 2 3)



 RESULT:-

CONCLUSION:-
We learned about writing the recursive LISP function which appends two lists together
