CP hasn't been kind towards me this past month.
Its been quite some time that a contest hasn't left me frustrated with my performance. Thank you.
I personally enjoyed it, and can now end the year on a positive note.

    Sorry for that, we made it independently and didn't expect link cut tree solution; yeah our solution is little simple based on Query Sqrt decomposition.
