So I have this text file:
Bob Joe Steve
Joe Bob Mark
Joe Steve Fred
Fred Fred Joe
And I am reading and counting the names with this program:
use 5.12.4;
use strict;
use warnings;
my %wordcount;
open(FILE, "names.txt") or die "Could not open file: $!";
while(my $line = <FILE>) {
chomp($line);
my @words = split(' ', $line);
foreach my $word(@words) {
$wordcount{$word} += 1;
}
}
sub hashDescend {
$wordcount{$b} <=> $wordcount{$a};
}
foreach my $key (sort hashDescend (keys(%wordcount)) {
print "Word: $key \t\t\t\t\t\t Count: " . ($wordcount{$key}) . "\n
+";
}
But now I want to change it up. I am going to be running this program in a huge repeating loop, so speed counts. So I want to make this faster.
I was thinking about making one big @globalarray and a @temparray and pushing from the @temparray into the global one. I am thinking this will make it a very tiny bit faster, but anything will do at this point. So how can I change my program as described, but still have the same output?

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
