I have the following code:
#!/usr/bin/perl -w
use strict;
my @array = ("11 12","11 13", "9 8 7", "3 4", "11 4") ;
my %gs_grp;
#print join("\n",(@array));
#recording index of the array for each shared number
my $count =0;
for my $key (@array){
my @gs = split(/ /,$key);
for my $gs(@gs){
push (@{$gs_grp{$gs}},$count);
}
$count++;
}
#combine index with shared number
my @sp = @array;
for my $gs(keys %gs_grp) {
my @tmp=();
for my $grp ( @{ $gs_grp{$gs} } ) {
next if(scalar @{ $gs_grp{$gs} }==1);
push(@tmp,split(/ /, ($array[$grp])));
splice(@sp,$grp,"");
}
my %duplicate = map { $_ => 1 } @tmp;
my @unique = keys %duplicate;
push(@sp,join(" ",@unique));
}
print join("\n", @sp);
print "\n";
The output from the above code is Not correct
The output I want is this:
3 4 11 12 13
9 8 7
Could anyone please help me here? Thanks

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).
