Re^4: removing reversed elements

I am sorry..i am getting following error message:

Can't locate Data/Dump.pm in @INC (@INC contains: /etc/perl /usr/local/lib/perl/5.10.1 /usr/local/share/perl/5.10.1 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.10 /usr/share/perl/5.10 /usr/local/lib/site_perl /usr/local/lib/perl/5.10.0 /usr/local/share/perl/5.10.0 .) at test.pl line 1. BEGIN failed--compilation aborted at test.pl line 1.

The code is very high level to people like me..if you would not mind, could you comment it please..

Data::Dump is just to dump out the array, so you could see, that the function does what you want. You could omit using it and pp-line too. AFIU grep here triggers counters, so it can throw away pairs already seen.	[reply]
