title: How do I reverse this hashing function?
body: <p>The idea is to get what is the 7 characters long string that produces this number: 3552907293224 with this script:</p>
  
  <pre><code>sub hash {
       my $nr = 13;
       for (split //, shift) {
            $nr = $nr * 43 + index("acdegijmnoprstuw", $_);
       }
       return $nr;
  }
  </code></pre>
  
  <p>I managed to figure out the string it's "eddigjo" (with manual trying), but I need a function that reverse traces what could possibly genereate the number mentioned above.</p>
