  1. JAZYKY UMELEJ INTELIGENCIE Common LISP Zoznamy Marian.Mach@tuke.sk http://neuron.tuke.sk/~machm Február, 2011 Katedra kybernetiky a umelej inteligencie FEI, TU v Košiciach

  2. Vytvorenie zoznamu • (list 1 2 3 4) • (list '(1 2 3 4)) • (list) • (list 1 (list 2 3) (list) (list 4)) • (make-list 4) • (make-list 4 :initial-element 2) • (setf x (list 1 2 3)) • (copy-list x) Katedra kybernetiky a umelej inteligencie FEI, TU v Košiciach

  3. Testovanie zoznamov • (listp '(1 2 3)) • (listp nil) • (listp 'jano) • (listp 3) • (null '(1 2 3)) • (null '()) • (equal '(1 2) (list 1 2)) Katedra kybernetiky a umelej inteligencie FEI, TU v Košiciach

  4. Rozoberanie zoznamu • (car '(1 (2 3) NIL (4))) • (cdr '(1 (2 3) NIL (4))) • (cdr '(1)) • (car nil) • (cdr nil) • (car (cdr (car (cdr '(1 (2 3) NIL (4)))))) • (cadadr '(1 (2 3) NIL (4))) Katedra kybernetiky a umelej inteligencie FEI, TU v Košiciach

  5. Alternatíva k car a cdr • (first '(1 (2 3) NIL (4))) = car • (second '(1 (2 3) NIL (4))) = cadr • (third '(1 (2 3) NIL (4))) = caddr • … • (tenth '(1 (2 3) NIL (4))) • (rest '(1 (2 3) NIL (4))) = cdr Katedra kybernetiky a umelej inteligencie FEI, TU v Košiciach

  6. Zovšeobecnené rozoberanie spredu • (nth 0 '(1 2 3)) = car • (nth 3 '(1 2 3)) • (nthcdr 0 '(1 2 3)) • (nthcdr 1 '(1 2 3)) = cdr • (nthcdr 3 '(1 2 3)) Katedra kybernetiky a umelej inteligencie FEI, TU v Košiciach

  7. Zovšeobecnené rozoberanie zozadu • (last '(1 2 3)) = nthcdr (dlz-1) • (last '()) • (last '(1 2 3) 2) = nthcdr (dlz-2) • (last '(1 2 3) 0) = nthcdr (dlz-0) • (butlast '(1 2 3)) • (butlast '(1 2 3) 2) Katedra kybernetiky a umelej inteligencie FEI, TU v Košiciach

  8. Rozširovanie zoznamu • (cons 1 '(2 3)) • (cons 1 nil) • (cons '(1 2) '(3 4)) • (append '(1 2) '(3 4) '(5 6)) • (append '(1 2) nil '(5 6)) • (append) • (list-length '(1 2 3)) Katedra kybernetiky a umelej inteligencie FEI, TU v Košiciach

  9. Hľadanie prvku • (member 2 '(1 2 3)) • (member 2 '(1 4 3)) • (member '(2) '((1) (2) (3)) ) • (member '(2) '((1) (2) (3)) :test #'equal) • (member 2 '((a 1) (b 2) (c 3)) :key #'cadr) Katedra kybernetiky a umelej inteligencie FEI, TU v Košiciach

  10. Rôzne užitočné funkcie • (remove 2 '(1 2 3 2 1)) seq • (remove 2 '(1 2 3 2 1) :count 1 :from-end t) • (remove 2 '(1 2 3 4 5) :start 1 :end 2) • (remove 2 '((1 3) (3 1)) :test #'< :key #'car) • (reverse '(1 2 3)) seq • (length '(1 2 3)) seq • (subseq '(1 2 3 4) 1) seq • (subseq '(1 2 3 4) 1 3) Katedra kybernetiky a umelej inteligencie FEI, TU v Košiciach
