Note that your solution divides the data differently than the OP's code. Use 1+$#x/2 instead of @x/2 to get the OP's result.

You can also write it 

sub split_array_in_two{ \@_, [splice @_, 1+$#_/2] }

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
