Perl, convert hash to array

Question

If I have a hash in Perl that contains complete and sequential integer mappings (ie, all keys from from 0 to n are mapped to something, no keys outside of this), is there a mean

Answer 1

As DVK said, there is no built in way, but this will do the trick:

my @array = map {$hash{$_}} sort {$a <=> $b} keys %hash;

or this:

my @array;

keys %hash;

while (my ($k, $v) = each %hash) {
    $array[$k] = $v
}

benchmark to see which is faster, my guess would be the second.
