sorting a hash / 2008-06-01


I want to sort a hash. The hash contains a list of cities and their
temperature and I want the 4 cities with max temp. The problem is that
the city-names are one extra level deep with the state-name coming in-
between. I wondered whether I should build the hash differently. A
different format would be: state_city, with the underbar separating
the state and the city.
$hash{Calif_Cupertino}{max_temp} = 38 ;
instead of
$hash{Calif}{Cupertino}{max_temp} = 38 ;


my %hash = () ;
$hash{Calif}{San Jose}{max_temp} = 84 ;
$hash{Calif}{San Fran}{max_temp} = 94 ;
$hash{Calif}{Cupertino}{max_temp} = 38 ;
$hash{Calif}{Fremont}{max_temp} = 66 ;
$hash{Texas}{Dallas}{max_temp} = 72 ;
$hash{Texas}{Austin}{max_temp} = 96 ;
$hash{Texas}{Fort Worth}{max_temp} = 62 ;
$hash{Mass}{Boston}{max_temp} = 96 ;
$hash{Mass}{Framingham}{max_temp} = 55 ;
$hash{Mass}{Worcester}{max_temp} = 55 ;

How do I sort this hash, please?
Thanks in advance.
