I'm familiar with assigning to slices of a hash, and its use in this line:

@seen {$t, $h, $r, $e} = ();

was very clever. However, why did you use slices in these lines?

@seen {$n,} = (); .... @seen {$o,} = ();
Aren't they equivalent to:
$seen{$n} = undef; $seen{$o} = undef;
Or even just:
@seen {$n} = (); # note the lack of comma after $n .... @seen {$o} = ();
I guess its that trailing comma that looks odd to me.

p.s. props on the @HIGH and @LOW generation... very sneaky!

to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • 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).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
