How do you print the key(s) of the largest value in a hash? I have a script that counts the occurences of something and the occurences it the value of that key.
Key -> Value
red -> 2
pink -> 1
orange -> 4
black -> 3
blue -> 4
And I need it to determine the greatest value, sort by it and only print the highest keys/value. In this example the highest value is 4 shared by ORANGE and BLUE. I need it so it just prints these two hash elements.
Whether it's just one highest value or if X number share it, all the highest valued key/value pairs need to be sorted.
I am very confused at how to do this.

taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
