sub this{
    my ($input) = @_;

    my %hash = (hash => example);
    my @array = qw(array example);
    my $scalar = "scalar example";

    query(%hash); #renamed get_data to query ;)
    query(@array);
    query($scalar);
}

sub query{
    my ($var) = @_;

    my $data_type = ref($var);
    if($daya_type eq 'ARRAY'){ print "is array\n"; return @array }; #d
+o functions here for get_array
    if($data_type eq 'HASH') {print "is hash\n"; return %hash }; #do f
+unction here for get_hash
    .... ect ....
}

this is untested as well, just as example to understand what i mean
