Example.
		   ?- my_write([a,b,c]).
		   a
		   b
		   c
		   true.
		
		Solution1.

		  my_write([]).
		  my_write([X|R]):- write(X),nl,my_write(R).

		Solution2.

		my_write(L):- member(X,L),write(X),nl,fail.
				
		Remember how member/2 works?
		
		member(X,[X|_]).
		member(X,[_|T]):- member(X,T).
