That helps, thanks!
However, I still get an error "Use of uninitialized value in numeric comparison (<=>)" and it seems like the loop never ends...
@AoA[0..$#AoA] = sort { $b->[0] <=> $a->[0] } @AoA[0..$#AoA];
my %seen = ();
my $j = 0;
while ($j < $#AoA) {
my $b = $AoA[$j][1];
my $c = $AoA[$j][2];
if ( ! $seen{$b}++ ) { # $b not seen before
DO STH WITH $b AND $c
$seen{$b}++;
} else { #seen $b before
my ($b, $a) = RESAMPLE;
$AoA[$j][0] = $a;
$AoA[$j][1] = '$b';
@AoA[$j..$#AoA] = sort { $b->[0] <=> $a->[0] } @AoA[$j..$#AoA]
+;
}
}
...any ideas?

Are you posting in the right place? Check out Where do I post X? to know for sure.

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).
