ok

hdb have burned me on time..

This is my first math script. Any math or Perl suggestion welcome!

`#!/usr/bin/perl
use strict;
use warnings;
{
my @tartaglia ;
sub tartaglia {
my ($x,$y) = @_;
if ($x == 0 or $y == 0) { $tartaglia[$x][$y]=1 ; return 1};
my $ret ;
foreach my $yps (0..$y){
$ret += ( $tartaglia[$x-1][$yps] || &tartaglia($x-1,$yps) );
}
$tartaglia[$x][$y] = $ret;
return $ret;
}
}
sub tartaglia_row {
my $y = shift;
my $x = 0;
my @row;
$row[0] = &tartaglia($x,$y+1);
foreach my $pos (0..$y-1) {push @row, &tartaglia(++$x,--$y)}
return @row;
}
for (0..5) {print join ' ', &tartaglia_row($_),"\n"}
print "\n\n";
print &tartaglia(3,3),"\n";
my @third = &tartaglia_row(5);
print "@third\n";
`

there are no rules, there are no thumbs..
