One more thing here, Let's say I get key/values as below in my hash

Where a certain value appears twice for different keys, for e.g. 'Eufaula' is a value for key 'Alabama' & 'California'

Likewise, 'Beacon' appears for both 'New York' & 'Utah'

Can i delete this for one key only (no particular where i need to retain this value for which key, just need once in any key) 

my $HASH1 = {
'Alabama'    => ['Andalusia', 'Anniston', 'Clanton', 'Eufaula', 'Aubur
+n'],  
'California' => ['Barstow','Eufaula'],
'New York'   => ['Amsterdam','Coney Island','Beacon'],
'Utah'       => ['Beacon','Layton']
};

so my result hash should look like 

my $HASH1 = {
'Alabama'    => ['Andalusia', 'Anniston', 'Clanton', 'Eufaula', 'Aubur
+n'],
'California' => ['Barstow'],
'New York'   => ['Amsterdam','Coney Island','Beacon'],
'Utah'       => ['Layton']
};

Thanks.
