Another way to do it (works!)
use strict;
my @height = qw/ 10 15 25 30 10 13 /;
my $columns = 3;
my @Best = ();
my $Min_height = 1E9;
my $Table_height = 0;
&check_columns;
foreach my $y (0..$Table_height) {
foreach my $x (0..$columns) {
my $data = ${$Best[$x]}[$y];
print defined $data ? $data : " ";
print " ";
}
print "\n";
}
sub check_columns {
my $pcat = ( shift or [ 0 .. $#height ] );
my @a = @$pcat;
my @b = ();
map {
push @b, shift @a;
my @result = ( [@a], [@b], @_);
if ($#result == $columns) {
my $max_height = 0;
my $table_height = 0;
foreach my $j (@result) {
my $height = eval join '+' => @height[@$j];
$max_height = $height if $height > $max_height;
$table_height = $#{@$j} if $table_height < $#{@$j};
}
if ($max_height < $Min_height) {
$Min_height = $max_height;
@Best = @result;
$Table_height = $table_height;
}
}
else {
check_columns(@result);
}
} @a;
}
Update: I should have used for (@a) instead of map.

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).
