You don't seen to have read my code closely enough. Specifically, you missed that I capture one short of the whole sequence.
Why? If the full string is "123", then the result should be 3.
For "123", "12" is captured and length("12") + 1 is 3.
If it's "21234", then the result should be 4.
For "21234", "123" is captured and length("123") + 1 is 4.
Still need to take overlaps into account even if you just want the length.
True, but I avoided needing to capture the same digit twice, and thus I avoided the need to visit the string twice.
you use min instead of max.
Thanks, fixed.

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).
