        # Using Explicit Initialization
        my %hash;
        $hash{'key1'} = 'value1';
        
        # Without autovivification - check if key exists before assigning
        if (!exists $hash{'key2'}) {
            $hash{'key2'} = {};
        }
        $hash{'key2'}{'subkey1'} = 'value2';

        # Output the structure
        use Data::Dumper;
        print Dumper(\%hash);
