Re^2: Tree Structure Challenge

How should I run your solution to get the result for the following?

'Zoo'->diff( 'Zoo'->new(qw( Dog Fox Wolf )),
             'Zoo'->new(qw( Fox )));

Not saying that I'm getting

Can't use an undefined value as an ARRAY reference at ./zoo.pl line 40

How should I run your solution to get the result for the following? What should the result look like? Not saying that I'm getting ... Huh? `dd( deeef( qw/ Dog Fox Wolf / ) ); __END__ ( ["Dog", "Canine", "Mammal"], ["Fox", "Canine", "Mammal"], ["Wolf", "Canine", "Mammal"], )` [download]	[reply] [d/l]

What should the result look like? `( [], [ 'Dog', 'Wolf' ] )` [download] Huh? I know how to run your code. It doesn't follow the specification: you haven't implemented a static method.

I know how to run your code. Its right there in the code It doesn't follow the specification: you haven't implemented a static method. I didn't implement a static method because its just extra indirection -- the spec contains enough indirection on its own, it doesn't benefit from extra confusion Speaking of which, you say it should return `( [], [ 'Dog', 'Wolf' ] )` [download] That is kind of a surprise compared to your original sample data and sample ooutput ... as it stands my "solution" isn't there yet	[reply] [d/l]
