Re: Can not print hash element

[lamp]

use Data::Dumper module for debugging these kind of issues. The following is the output of '%table' hash using Data::Dumper before removing the space from your input. You can find spaces in front of all the country names.

use Data::Dumper;
print Dumper(%table);

output

$VAR1 = ' Germany';
$VAR2 = [
          'Frankfurt',
          'Berlin'
        ];
$VAR3 = ' Finland';
$VAR4 = [
          'Helsinki'
        ];
$VAR5 = ' USA';
$VAR6 = [
          'Chicago',
          'Washington',
          'New York'
        ];
