To repeat a node above, doing this with regex seems a little odd. Anyway, I thought I would take 5 and have a go. I did mine with look behinds (cos I rarely get to use them and its different to your solution). Not sure if my attempt is bone headed :). Still . . . here it is:
use strict;
use warnings;
my @nums;
for(my $i = -100; $i < 400; $i++)
{
push @nums, $i;
}
foreach my $n (@nums)
{
if($n =~ /^[012]?(((?<=2)[0-5])|(?<!2)[0-9])?(((?<=25)[0-5])|(?<!2
+5)[0-9])$/)
{
print $n, ": pass\n";
}
else
{
print $n, ": fail\n";
}
}
HTH

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).
