A simple way to do this is
my @a = (1..16);
my $kid_size = 3;
my $num = int(@a/$kid_size);
my @b;
foreach my $i (0..$num-1) {
$b[$i] = [splice @a,0,$kid_size];
}
$b[$num] = [@a];
foreach my $i (0..$num) {
print "b($i): ", join(",", @{$b[$i]}), "\n";
}
Here I create an array of arrays $b[$i][$j] that is convenient for storing the babies.

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).
