Hi, I need to split an array into 4 even arrays (lists). I wrote this little piece of code I called "poor man's round robin algorithm". I wonder if there is a better approach to this ?
Here's the code
#!/bin/perl
my @array = qw(1 2 3 4 5 6 7 8 9 10 11 12);
my $counter = 1;
my $data;
for my $pos (0 .. $#array) {
print $array[$pos],"\n";
push @{$data->{$counter}}, $array[$pos];
if ($counter == 4) {
$counter = 1;
} else {
$counter++;
}
};
use Data::Dumper;
print Dumper($data);
Here's the output
1
2
3
4
5
6
7
8
9
10
11
12
$VAR1 = {
'4' => [
'4',
'8',
'12'
],
'1' => [
'1',
'5',
'9'
],
'3' => [
'3',
'7',
'11'
],
'2' => [
'2',
'6',
'10'
]
};

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).
