See How can I remove duplicate elements from a list or array? From perlfaq4, How to find and remove duplicate elements from an array? or many other places. Are we to take it that you have not made a new years resolution to read the documentation, search for answers by yourself or even try something out and benchmark it? You asked something similar in Find array duplicates, several years ago.
