What do you mean with merging the values.
For every key, there will be only one value in the result.
E.g. if you want to calculate the average of the values,
the following snippet will do:
my %merged_hash = %hash1;
while (my ($key, $val) = each %hash2) {
defined $merged_hash{$key} ?
$merged_hash{$key} = ($val + $merged_hash{$key}) / 2 :
$merged_hash{$key} = $val;
}
