      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);
