Maybe this will help? #! perl -slw
use strict;
use Data::Dump qw[ pp ];
use List::Util qw[ sum ];
use constant WINDOW => 10;
my @data = map int( rand 10 ), 1 .. 30;
my @mAves;
my @slide;
for my $dp ( @data ) {
push @slide, $dp;
shift @slide if @slide > WINDOW;
push @mAves, sum( @slide ) / WINDOW if @slide == WINDOW;
}
print join ' ', @data;
print join ' ', @mAves;

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).

or How to display code and escape characters
are good places to start.
