Re: Out of Memory

Use a trie instead of a hash table.

For future reference,

    if(exists $wordCount{$_}) {
        $wordCount{$_} = $wordCount{$_} + 1;
    }
    else {
        $wordCount{$_} = 1;
    }

can be shortened to

    ++$wordCount{$_};

It won't help your memory problem, just your code clarity.

That is indeed an implementation of the previously mentioned data structure. I've never used it or other modules, thus the lack of recommendation.	[reply]
