Sunday Push Won by David Jones

Unstoppable contest force David Jones won the Big Push by making the greatest cumulative improvement to the top score on Sunday. SY was close behind him, submitting an entry that would have put him in first place one second after the midnight deadline. Ouch! Sunday also saw significant contributions from Jan Langer, YC, Fel, and MikeR.

    As I usually do, I’ve now posted a heavily commented version of the leading code so that those of you who aren’t in the ‘thick of it’ can have an opportunity to understand the alogrithms behind the solutions to this problem.

    The code is entry 47616 viewable at:

    Hope this helps!

Wrap code fragments inside <pre> tags, like this:

<pre class="code">
a = magic(3);
sum(a)
</pre>

If you have a "<" character in your code, either follow it with a space or replace it with "&lt;" (including the semicolon).
