# Sample Perl code using references my $array_ref = [1, 2, 3, 4, 5]; my $hash_ref = { key1 => 'value1', key2 => 'value2' }; sub process_array { my ($arr_ref) = @_; return scalar(@$arr_ref); # Returns the count of elements in the array } sub process_hash { my ($hash_ref) = @_; return scalar(keys %$hash_ref); # Returns the count of keys in the hash } print process_array($array_ref); # Output: 5 print process_hash($hash_ref); # Output: 2
