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";
Output:
n1: 81658500
n2: 81658500

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).

or How to display code and escape characters
are good places to start.
