Passing Temple Queues using treaps

I have passed Temple Queues on SPOJ in 1370ms, but I’m curious if it can be optimized so much as to pass the same question on Codechef in less than 400ms.

I have already spent too much time optimizing but can’t get any more improvement than this. Please give optimization tips/tricks :slight_smile:

[I know the solution using BIT, I just really want to optimize my treap implementation as much as possible]
