Hi,
For me the same code is working
my @match_to_array = (a,b,c,a,d,c,b,r);
my %seen = ();
my @r = ();
foreach my $a (@match_to_array) {
unless ($seen{$a}) {
push @r, $a;
$seen{$a}++;
}
}
print "@r";
print "\n@match_to_array";
Can you explain how it is not working , with actual and expected output.

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).

are good places to start.
