Ruby solution: https://gist.github.com/1087583
I acutally don't know Ruby that well, but it looks like your program
recognizes "[(])" as correct although it is not, because you translate
"[(])" to "(())" (which is indeed correct, but does not resemble the
input correctly anymore).
Right you are. The optimization breaks the logic. Good catch!
Turns out with a little possessiveness I can fix my original approach
which has the added benefit of not needing three passes through the file
(the two #tr's are obsolete now).
