Set symmetric difference

[Pradosh Kumar Mohapatra <pmohapat@eecs.uic.edu>]

Hi,
I am a graduate student at the University of Illinois at Chicago. I am
currently doing some research in which I need answer to the following
question:

"If I have two sorted arrays, can I find symmetric difference of the two
in time poly(log)?"
Or more generally, if the elements of two sets are in sorted order, can
I perform various set operations like union, intersection or symmetric
difference in logarithmic time?

I would be very very grateful if you could answer my question. I am
stuck on this for a long time.

Thanks and Regards,
Pradosh
