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.
Break And Fix The Tree is same as this which is also recommended in USACO link cut tree problems. But good to know expected soln was different.
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.
