Re^2: Stuck on a Perl assignment

I am still struggling with this code .. i cant figure out much after going through documentation ... this method works whats the error in this ..

#!/usr/bin/perl
use strict;
use warnings 'all';
    my    $structure = [ { a => 1, b => 2, c => 3 }, { d => 4, e => 5 
+}, [ 6, 7, 8 ], 9, 10, 11, [ 12, 13, 14 ] ];
    
    sub addtwo {
        
    my $params = shift;
     my $s = $params->{$structure};
    
    if (ref($s) eq "ARRAY") {
         my $c = 0;
        foreach my $e (@{$s}) {
            $s->[$c] = addtwo({ structur => $e });
            $c++;
        } 
    } elsif (ref($s) eq "HASH") {

        if (scalar keys %{$s} == 0) {
            return undef;
       } else {
            foreach my $e (values %{$s}) {
                $s->{$e} = addtwo({ structure => $s->{$e} });
            }
        }
    
    } else {
        $s = 1;
    }
    
    return my $c;
}

A hash key is always a string. What do you the following does when `$structure` is an array reference? `my $s = $params->{$structure};` [download] ($q=q:Sq=~/;[c](.)(.)/;chr(-\|\|-\|5+lengthSq)`"S\|oS2"`map{chr \|+ord }map{substrSq`S_+\|`\|}3E\|-\|`7**2-3:)=~y+S\|`+$1,++print+eval$q,q,a, [download]	[reply] [d/l] [select]
