SPOJ Problem - ORDERSET

Hey can anyone please help me with this problem. I’m repeatedly getting wrong answer. I think this question is a implementation of augmenting data structures as described in cormen. I have done the same. I have implemented a Red Black Tree with size attribute so that i can find the Kth order statistic. I have tested my code with many inputs its giving correct answer i suppose. Please can any one give me any test case where my code gives WA.
Thanks

Try the test case given there. I’m stuck with the same problem. I’m trying a simpler BIT implementation with co-ordinate compression and offline processing. Still debugging the code.
