in reply to @$ variable type

A few things you can do to make it easier to learn what's going on with your code. At the top of your file, along with other pragmas include:

  • use diagnostics -v; use Data::Dumper; ### YOUR CODE ### print Dumper(@$sets);
    • The first line will give you more debugging information on any errors/warnings your code is returning.
    • The second (use Data::Dumper) will reveal the contents of variables such as your @$sets, using print Dumper(@$sets);

References in Perl can be hard to learn (as can navigating Perl's documentation) but it's important you do so in order to not struggle with the language. Good luck!
