Need Help??

in reply to Re: How to combine two different hashes into single hash.
in thread How to combine two different hashes into single hash.

Thanks Rolf,

Firstly, I should convert hash of hashes into hash and then use join ?

my $VAR1 = {'Tim' => {'abc' => 7, 'def' => 7, 'ghi' => 0 }, 'Adam' => 
+{ 'abc' => 0, 'def' => 0, 'ghi' => 0 }, 'keas' => { 'abc' => 0, 'def'
+ => 0, 'ghi' => 0 }};

my %h1 = ('Tim' => {'abc' => 7, 'def' => 7, 'ghi' => 0 }, 'Adam' => { 
+'abc' => 0, 'def' => 0, 'ghi' => 0 }, 'keas' => { 'abc' => 0, 'def' =
+> 0, 'ghi' => 0 });

The following is a variant for references:

use strict;
use warnings;
use Data::Dump qw/pp dd/;


my $h1 = {
    'Tim' => {
        'abc' => 7,
        'def' => 7,
        'ghi' => 0
    },
    'Adam' => {
        'abc' => 0,
        'def' => 0,
        'ghi' => 0
    },
    'keas' => {
        'abc' => 0,
        'def' => 0,
        'ghi' => 0
    }
};

my $h2 = {
    'Dav' => {
        'jkl' => 12,
        'mno' => 34,
        'pqr' => 45
    },
    'Adam' => {
        'jkl' => 7,
        'mno' => 0,
        'pqr' => 7
    }
};

my %joined_1st = (%$h1,%$h2);

#pp \%joined_1st;

my $joined_2nd =
    {
        map { $_ => { %{ $h1->{$_} // {} }, %{ $h2->{$_} // {} } } }
            keys %joined_1st
    };


pp $joined_2nd;
