Clever idea to generate buzz while making an impact.<p>Edit, took a shot at it:<p>Is there something wrong with how you're running the scripts? My Python script seems to die saying:<p><pre><code> No such file or directory: '/opt/puzzles/*.in'
</code></pre>
But your example on how you're going to run it on the bottom says you will specify an actual file rather than a wildcard. Running it locally on my machine on all your tests results in this:<p><pre><code> $ python test.py d.in > d_me.out
$ md5 d.out
MD5 (d.out) = c6dc722a7020baacebd876d4377065ad
$ md5 d_me.out
MD5 (d_me.out) = c6dc722a7020baacebd876d4377065ad
</code></pre>
So I doubt it's a silent failure in my code.
