in reply to help with simplifying program

Hi There, I'm not sure, if the unless condition is actually filtering anything:

use strict;

my $n1;
my $n2;

foreach my $w (3..100) {
    foreach my $x (2..$w-1) {
        foreach my $y (1..$x-1) {
            foreach my $z (0..$y-1) {
                foreach my $s (1..20) {
                    $n1++;
                    unless ( $x == $w + $s
                             && $y == $x + $s
                             && $z == $y + $s ) {
                        $n2++;
                    }
                }
            }
        }
    }
}

print "n1: $n1\n";
print "n2: $n2\n";
