Virtual Tree
We query and multi-point came from a tree dp we can re-run the actual construction of the virtual tree used in the maintenance of some trees and other things

Today's experience:
When asked to do some more times the size of the problem should pay attention to the complexity of the memset, etc.
In dealing with some tree line, we can not use simple tags to achieve pruning lazy, then we should consider some properties such as the maintenance interval root and hdu score more than last year and other school issues
