Is there a way to compare the values of one hash (while looping through the hash) and determine how many times
a value has occurred in the hash?

$hash = (
     key1 => 10,
     key2 => 10,
     key3 => 3,
     key4 => 5,
     key5 => 10
);

In the hash, above, there are 3 occurrences of the value 10. I need to do this in order display the value
that has the highest frequency. Perhaps, there is a way to loop through the hash to compare the current
value to the previous value, then increment a counter variable by 1?

Any suggestions?

Thanks.
