Neat problem. Here is my initial crack at it:
use strict;
use Data::Dumper;
my $string =' aaaa bbbbccccccccbbbb aaaabbbbbcdddddddddddddddd
+dddd';
my @bah;
my $old_pos = 0;
while ($string =~ /((.)\2*)/g) {
push @bah, [$2,$old_pos,length($1)];
$old_pos = pos($string);
}
print Dumper(\@bah);
I am really interested as to how the benchmarking turns out. Let us know. Update: It is late, but I just realized i would probably benchmark all the code that turns up on this post anyhow. Once again interesting problem. Updated Again: Changed the \2+ to \2* or it would have failed when there was a series one character long.

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).
