The basic process is still the same. You record what you have seen and make processing decisions based on that data.

doSomething($data) unless $seen{$key}++

Providing appropriate values for $key, doSomething(), and $data are left as an exercise for the reader.

Update: Perhaps I am misunderstanding your question. Please post what you expect to see as output given the provided input data.
