You are given a tree (an acyclic undirected connected graph) with n nodes. The tree nodes are numbered from 1 to n.
Each node has a color, white or black, and a weight.
We will ask you to perfrom some instructions of the following form:
0 u : ask for the maximum weight among the nodes which are connected to u, two nodes are connected if all the node on the path from u to v (inclusive u and v) have a same color.
1 u : toggle the color of u(that is, from black to white, or from white to black).
2 u w: change the weight of u to w.
Multicase.
The first line contains a number n denoted how many nodes in the tree(1 ≤ n ≤ 10
5). The next n - 1 lines, each line has two numbers (u, v) describe a edge of the tree(1 ≤ u, v ≤ n).
The next 2 lines, each line contains n number, the first line is the initial color of each node(0 or 1), and the second line is the initial weight, let's say Wi, of each node(|W
i| ≤ 10
9).
The next line contains a number m denoted how many operations we are going to process(1 ≤ m ≤ 10
5). The next m lines, each line describe a operation (t, u) as we mentioned above(0 ≤ t ≤ 2, 1 ≤ u ≤ n, |w| ≤ 10
9).
For each query operation, output the corresponding result.
