Just change all your

(<' ') does not match (<'') .

Subject: [Jprogramming] Who owns the zebra? with J
I stumbled across this Stackoverflow question[0], based on an old puzzle, and I
really liked some of the answers. And of course, I started thinking how to do
it in J.
Has anyone written a J solution to this problem?
