I Have an Array of Arrays which looks like this:- 
@ICE =
30F-WKS(tab)`1781183799.xxxx1' (tab)     IC---;
30F-WKS  (tab)   `1781183799.xxx11'  (tab)    IC---;
ADM34A3F9  (tab) `1781183799.41455'  (tab)    IC---;

[download]
IF TWO RECORDS EXIST FOR THE SAME INSTANCE.I WANT TO KEEP THE FINAL RECORD AND REMOVE THE PREVIOUS RECORDS. FOR EXAMPLE, COMPUTER 30F-WKS HAS TWO RECORDS.I WANT TO REMOVE THE FIRST RECORD AND KEEP THE SECOND.

The result will be:- 

ICE=
30F-WKS  (tab)   `1781183799.xxx11' (tab)     IC---;
ADM34A3F9  (tab) `1781183799.41455'  (tab)    IC---;

I have used the following code:
my @ICEU; 
my %seen;

my @ICEU = grep { !$seen{$_->[0]}++ } @ICE;

print Dumper \%seen;

The output I am getting is:-

$VAR1 = {
          '' => 1218
        };

Your advise will be appreciated
