You are given a tree of $$$n$$$ nodes. The tree is rooted at node $$$1$$$, which is not considered as a leaf regardless of its degree.

Each leaf of the tree has one of the two colors: red or blue. Leaf node $$$v$$$ initially has color $$$s_{v}$$$.

The color of each of the internal nodes (including the root) is determined as follows.

Let $$$b$$$ be the number of blue immediate children, and $$$r$$$ be the number of red immediate children of a given vertex.
Then the color of this vertex is blue if and only if $$$b - r \ge k$$$, otherwise red.

Integer $$$k$$$ is a parameter that is same for all the nodes.

You need to handle the following types of queries:

1 v: print the color of node $$$v$$$;
2 v c: change the color of leaf $$$v$$$ to $$$c$$$ ($$$c = 0$$$ means red, $$$c = 1$$$ means blue);
3 h: update the current value of $$$k$$$ to $$$h$$$.

Input

The first line of the input consists of two integers $$$n$$$ and $$$k$$$ ($$$2 \le n \le 10^{5}$$$, $$$-n \le k \le n$$$) — the number of nodes and the initial parameter $$$k$$$.

Each of the next $$$n - 1$$$ lines contains two integers $$$u$$$ and $$$v$$$ ($$$1 \le u,v \le n$$$), denoting that there is an edge between vertices $$$u$$$ and $$$v$$$.

The next line consists of $$$n$$$ space separated integers — the initial array $$$s$$$ ($$$-1 \le s_i \le 1$$$). $$$s_{i} = 0$$$ means that the color of node $$$i$$$ is red. $$$s_{i} = 1$$$ means that the color of node $$$i$$$ is blue. $$$s_{i} = -1$$$ means that the node $$$i$$$ is not a leaf.

The next line contains an integer $$$q$$$ ($$$1 \le q \le 10^5$$$), the number of queries.

$$$q$$$ lines follow, each containing a query in one of the following queries:

1 v ($$$1 \le v \le n$$$): print the color of node $$$v$$$;
2 v c ($$$1 \le v \le n$$$, $$$c = 0$$$ or $$$c = 1$$$): change the color of leaf $$$v$$$ to $$$c$$$ ($$$c = 0$$$ means red, $$$c = 1$$$ means blue). It is guaranteed that $$$v$$$ is a leaf;
3 h ($$$-n \le h \le n$$$): update the current value of $$$k$$$ to $$$h$$$.

Output

For each query of the first type, print $$$0$$$ if the color of vertex $$$v$$$ is red, and $$$1$$$ otherwise.
