( #3333=superdoc: print w/ replies, xml ) Need Help??

I haven't been able to get some of the answers to work. Maybe I have a different image of the data structure. Can somebody post what they've been working with?

Here's what I'm using to test:

$t = { d => 'd', l => { d => 'b', l => { d => 'a', l => 0, r => 0, }, r => { d => 'c', l => 0, r => 0, }, }, r => { d => 'f', l => { d => 'e', l => 0, r => 0, }, r => { d => 'g', l => 0, r => 0, }, } };

And here's a solution in 92 chars, that puts the tree into a single hash, and searches using the hash:

sub f{r(pop);$a{(pop)}||0;sub r{my$n=shift||return;$a{$n->{d}}=$n;r($n +->{l});r($n->{r});};};

Speak up if I missed something.
