I sorta like:
use strict;
use warnings;
my @array = (1 .. 8);
my @other;
while (@array) {
push @other, @array[-1, 0, 1, -2];
splice @array, 0, 2;
splice @array, -2, 2;
}
print "@other";
but it'd be nice to clean up the splices in some fashion. Of course if you don't want to destroy the original array you could:
use strict;
use warnings;
my @array = (1 .. 8);
my @other;
push @other, @array[-$_ * 2 - 1, $_ * 2, $_ * 2 + 1, -$_ * 2 -2]
for 0 .. $#array / 4;
print "@other";

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).
