Yes, I sensed a typo somewhere in your message.

With the array approach we don't have to know in advance how many elements are in the strings and we can loop through them without having to worry about that (with ALEN() function or FOR EACH construct). And one can even easily check if both strings have the same number of elements (don't know if this should add to the original problem's requisits).
