That's a nice approach.
If you want to extend it to negative numbers, it will be less work than you think if you use the right hack. As far as the difference is concerned, having, say, -16 in one partition is exactly the same as having 16 in the other one. So flip all of your signs to positive, then when you've found the solution, delete the appropriate positive ones from one partition while inserting negatives in the other. Voila! Rather than a pervasive logic change you just have to pre-process the list and post-process your answer.

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).
