Here's the algorithm:
use constant COL => 4;
my @data = qw( 10 15 25 30 10 13 );
my @cols = map [$_], @data;
while (@data > COL) {
my $i = 0;
my $s = $data[$i] + $data[$i+1];
for my $j (1 .. @data-2) {
($i, $s) = ($j, $data[$j] + $data[$j+1])
if $data[$j] + $data[$j+1] < $s;
}
splice @data, $i, 2, $s;
splice @cols, $i, 2, [@{ $cols[$i] }, @{ $cols[$i+1] }];
}

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).

or How to display code and escape characters
are good places to start.
