Re: How to get 2nd highest value from an array?

Update: Oops, i actually meant to say: Is there anyway to do this same thing on the values of a hash?

Do you mean just the values themselves or the keys based on the values? Here is some code for both cases:

my %hash = (
    4 => 20,    # second highest key
    2 => 40,    # second highest value
    3 => 30,
    1 => 50,
    5 => 10,
);

# second highest value
print ((sort values %hash)[-2]);

# key based on the second highest value
print ((sort { $hash{$b} <=> $hash{$a} } keys %hash)[1]);

For the second example, since we already have to specify a sort block, i choose to sort descending and use the subscript 1 and not -2. TIMTOWTDI. :)
