Thank you POJ. This really helped but i am still not able to figure out, how to print the duplicates? This way, only unique elements will be present in hash and i am successfully able to get the hash. Can you please help in providing how can i print which value/values are repeated for their respective keys?

Well, I need to print above according to this :

 ++$count2{$key}{$_} for @{$hash{$key}};
