Hi Experts,

I am using multidimensional hashes for the first time, and i have come across some issues, please suggest me some ideas to resolve

$VAR1 = 'FILE_A';
$VAR2 = {
          'CHECK_1' => {
                                     'JAPAN' => {
                                                         'A' => 1
                                                       },
                                     'CHINA' => {
                                                         'B' => 2
                                                       },
                                     'MALYA' => {
                                                         'C' => 1
                                                       },
                                     'EUROP' => {
                                                         'D' => 1
                                                       }
                                   }
        };
$VAR3 = 'FILE_B';
$VAR4 = {
          'CHECK_2' => {
                                     'JAPAN' => {
                                                         'A' => 1
                                                       },
                                     'CHINA' => {
                                                         'B' => 1
                                                       },
                                     'EUROPE' => {
                                                         'C' => 1
                                                       }
                                   }
[download]

Output what i got

FILE_NAME    A    B    C    D
CHECK        2    3    2    1
[download]

Output what i am expeting

FILE_NAME    A    B    C    D
CHECK        1    2    1    1
[download]

I am reading the data from two files and checking if data exist in other file, if exists then exclude those records while writing final output
