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.
