Ok, you have a little mistake here.. It's all in "Case2":

my $Rubbish=join "",(split //,shift)[$_[1]..$_[2]];

Ok, before that you have $_[0], $_1 and $_2. Then you shift. That means that you take the first value ($_[0]), end delete it. So $_1 becomes $_[0] and $_2 becomes $_1. And since there wasn't a $_3 there won't be a $_2 after that.
If you alter the line to the following it should work:

my $Rubbish=join "",(split //,shift)[$_[0]..$_[1]];
sorry, i made a mistake.. this WON'T work! see below..
