Re: Hints on recursion

Whoa Pascal !

First of all the problem should have been "..return true if a occurs
atleast twice in the list.." and not twice. My error = my apologies.
(Does this make it simpler?)

Im on page 15 of the book and I dont think they expected me to know all
that (Incidentally, Im just beginning with the basic constructs e.g
cons, car,cdr etc and dont know much) What is a DFA?
All in all its good to know I can get help here as I tread on the
supposedly rewarding path of lisp programming. Merci beaucoup pour
votre aide.
