I'm not sure whether this is in the rules but it does work. The code below sorts the data before matching. This makes the match fairly trivial since you need to look for the string abc without a an extra "a" or "c".
#! /usr/bin/perl -w
use strict;
my @testdata = qw (abc cba cab bac bba cbc bbc abcdefg 0a2c3bc);
foreach (@testdata) {
my $test = join '', sort split //, lc $_;
$test =~ /[^a]*abc(?!c)[^c]*/ ? print "Matched $_\n" : print "Didn
+'t match $_\n";
}

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).
