I have two arrays having the connection information "from -->to"
{@a=(a,b,d) ,
@b=(c,c,e)}
The following code finds the connected components based on the content of these two arrays.
Code
my @a=qw(a b d);
my @b=qw(c c e);
my $g = Graph->new( undirected => 1 );
for (my $r = 0; $r <= 2; $r++) {
$g->add_edge($a[$r], $b[$r]);
}
my @subgraphs = $g->connected_components;
my $V = $g->vertices;
print "\n$V\n";
print "----connected components------------";
use YAML; print Dump \@subgraphs;
------------OUTPUT----------------------
5
----connected components---------------
-
- c
- a
- b
-
- e
- d
My question is how do I access only one of the connected components? I.e. either C-A-B or D-E .
Also how do I find the total number of connected components.

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).
