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); }
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.
