Hard problem
Recently, I solved 342E - Xenia and Tree using Sqrt decomposition.
The problem have two types of queries: - Color node $$$x$$$ red - Find minimum distance to any red color
I thought, what will be the solution if there is query: $$$Color node x blue$$$.
I'm not sure if this is solvable using centroid decomposition, but is it solvable in anyway other than it?
