Tip: you can use recursion -- check only the first two characters of the
string, then ask your function to check the rest.

(It won't really be efficient in Ruby, because strings aren't lists, but
it'd be cute. (On the other hand, splicing a string in Ruby perhaps uses
copy-on-write so it may not be inefficient.))
