I think this is due to the fact that maybe the time complexity of your code is nlog^2q. Question requires it to be nlogq.
Try using fast i/o. I have also used similar approach and just using fast i/o might do it.
I tried same approach with segment trees and it failed :(
Yes, fenwick tree/BIT is faster than segment tree due to segment tree operations having larger constant factor. This question does have n,q = 1e6, and even BIT passes with around ~ 1s.
