Re: Removal of values in array from array list

in reply to Removal of values in array from array list

my %tocheck = map { $_ => 1 } @tocheck;
for (values(%checkfrom)) {
   @$_ = grep !$tocheck{$_}, @$_;
}

When I do that I get the error message:"Cant use string ("...") as an ARRAY ref while strict refs in use.

anyway I updated the post to give more insight into the question.

You were very vague about your input format. I assumed you meant:

my %checkfrom = (
    Meat  => [qw( Fish Apple Pork Bacon )],
    Fruit => [qw( Apple Pie Orange Beef )],
);
