This doesn't deal with duplicates. If you want to deal with duplicates, I think you change it to:
sub nn { @_{@_}=0;@_=sort{$a<=>$b}keys%_; $_[1]-$_[0]>$_[$_]-$_[$_-1]and@_[0,1]=@_[$_,$_-1]for 2..$#_; @_[0,1] }

That brings the total from 86 to 99. I'm not sure if the spec requires that duplicates be treated as one element or separate elements.
