Question: QTREE5
I have read a solution that uses Centroid Decomposition but was unable understand how the querying in Centroid Tree reflects the same in the original Tree?? Edges are changed.Path from u to v might not contain centroids why does that appraoch work?
Can someone help?
What's wrong with my question? Besides not getting any help, there are many downvotes. Can i know the reason please? I am losing trust in codeforces. Sorry.
It is because you are green.
