reverse iterator in google_dense_hash_set

I have working example for google_dense_hash_set, posted a code link of coliru but Coliru doesnt support google/dense lib

as google_dense_hast_set support forward iterator. but i want to access the values in reverse way.

click here for working example code.

is there any way so that i could store values directly in decreasing order or access through member function like rbegin()-->rend()
