Hi,

I made some changes as per my understanding, but i couldn't make changes in the code to reflect as per requirement.

...
if(exists($final->{$x[$i]})){
    print "second\n";
    $final->{$x[$i]} = ($final->{$x[$i]}, $f);  #### i need to push th
+e $f into $final.
}

Current output:

$VAR1 = \{ 'a' => { 'b' => 'abc' } };

Expected Output:

$VAR1 = \{ 'a' => { 'b' => 'abc' }, { 'c' => 'xyz' } };
