I agree with you and thank you, LanX, I am really not against using a HoH. But there are some cases where a HoH is really the natural data structure, and others where it is debatable. In this specific case, I would think that a HoH does not bring any algorithmic advantage (that's what I tried to show), so that using two hashes is simpler for the beginner. But I am perfectly happy with a HoH.
On your second point, well, yes, maybe, the only aim was just to print the output to show the results. The map function is the first one that came to my mind to format the output, using join is also a good possibility (perhaps a bit clearer to the beginner). But this is really just a result formatting issue. In brief, as we all know, TIMOWTDI.

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).
