Comment faire une fonction d'inversion de liste en Erlang ?
Raw
inv.erl
% Implementer :
% Spec : inv/1.
% inv(L) renvoie la liste inverse de L
%
% Exemple :
% inv([1,2,3]) = [3,2,1]
% Analyse
% sur L : 2 cas
% 1) L = [] : dans se cas renvoie d'une liste vide
inv([])->[];
% 2) L =/= [] : L = [Pr|Fin]
inv([Pr|Fin])->inv(Fin)++[Pr].
