Concatenation of Lists in Prolog

Question

Can someone help me find the error in these rules?

concat([], List, List).
concat([Head|[]], List, [Head|List]).
concat([Head|Tail], List, Concat) :- concat(         


        

Answer 1

It can be done by using append.

concatenate(List1, List2, Result):-
   append(List1, List2, Result).

Hope this helps.
