I can't see how you handled the idea of removing duplicates. I solved it using a offline approach. Quora has a nice tutorial on it.

It is harder than GSS3, GSS4 and GSS5. Maybe you want to try them first if you are going to solve them all.

    i also use offline. i sort the queries wrt right position. if any value appear previously I set 0 at the previous position of the segment tree, and insert the value at the current position. then i use GSS1.
