My own code, for a class I had

#!/usr/bin/perl -w
use strict;
han('A','B','C',$ARGV[0]);
sub han{
    return if $_[3] <= 0;
    han($_[0],$_[2],$_[1],$_[3]-1);
    print "Move disc $_[3] from $_[0] to $_[2]\n";
    han($_[1],$_[0],$_[2],$_[3]-1);
}
[download]

Number of discs is supplied as $ARGV[0] so, yeah. You could continue to play with this to see how much more it will compress. (I really didn't like the TA's for this class and eventually started using map and grep in all the programs.)

Edit:
made it shorter.

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 How to display code and escape characters are good places to start.
