%% This is a test file
%%
-module(test).
-export([nrev/1]).
%% Just a naive reverse function in order
%% to get a code example with some comments.
nrev([X | Xs]) ->
append(X, nrev(Xs)); % Quadratic behaviour
nrev([]) ->
%% The trivial case:
[].
%% We need `append' as a subroutine:
append(Y, [X | Xs]) ->
[X | append(Y, Xs)]; % Simple, innit?
append(Y, []) ->
[Y]. % Done.
