Finding identical entries in two arrays

I would like to know what would be the best way to find identical entries in two separate arrays?

I have ArrayA and ArrayB, each having a list of actors, I want to know how to find out if ArrayA and ArrayB have the same actor, and destroy it in the level.

Is it feasible?

Thanks!

Here are some array nodes.
