I have the numbers 1 to n UPDATE: n is always a multiple of four.
I want to arrange them in the order "highest, lowest, next-lowest, next-highest, next-highest, next-lowest, etc".
For instance, with the numbers one to eight I want "8,1,2,7,6,3,4,5".
This code gets the job done, but I feel it's clunky. Anyone got a smarter way?
my @array = ( 1 .. 8 );
my @other_array = ();
while (@array) {
if ( $array[0] % 2 ) {
push( @other_array, pop(@array), shift(@array) );
} else {
push( @other_array, shift(@array), pop(@array) );
}
}
print "@other_array";
Nobody says perl looks like line-noise any more
kids today don't know what line-noise IS ...

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).
