Sort hash twice
|
Can't Post

I am currently trying to take a hash which has words stored in the keys, and the number of occurences stored in the values. I want to output the key/value pairs so that the key/value pairs with the highest value are listed first, and of the key/value pairs that have the same value, I want to output those in alphabetical order with respect to their key's.
Example:
Input: c!c b!b a!a v!v v!v t!t t!t
Output: t!t:2, v!v:2, a!a:1, b!b:1, c!c:1
At the moment I am trying to use a foreach loop, but it's not working. The output is working numerically how I want, but not working lexically.
foreach my $word (sort { $wordHash{$b} <=> $wordHash{$a} || $wordHash{$a} <=> $wordHash{$b} } keys %wordHash)
{
print "$word:$wordHash{$word}\n";
