Alright, just an update. I believe I have found the problem.
use strict;
use Data::Dumper;
my $start = {};
sub add{
my $root = shift;
my $level = shift;
my @items = @_;
if(!@items) {return $level-1;}
#print "level = $level\n";
while(@items) {
my $first = shift @items;
$root->{$first}->{count}++;
if(!exists($root->{$first}->{children})) {$root->{$first}->{ch
+ildren}={};}
#print "\t" x $level . "first = " . $first . ", values = " . j
+oin(',',@items)."\n";
$root->{$first}->{max} = add($root->{$first}->{children}, $lev
+el+1, @items);
}
}
add($start, 1, 1..4);
add($start, 1, 1..2);
print Dumper($start);
I was passing hash reference that were undefined, which is not a good thing apparently. So, I fixed that problem.

Are you posting in the right place? Check out Where do I post X? to know for sure.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

Want more info? How to link
or How to display code and escape characters
are good places to start.
