You are given an undirected tree with $$N$$ nodes rooted at node 1. Every node has a value $$A[i]$$ assigned to it. You are required to answer $$Q$$ queries of the following type:

• $$U V X$$
  • Select a subtree with $$U$$ as the root node and subtree with $$V$$ as the root node and swap their positions. That is, detach both the subtrees and swap their positions.
  • If node $$U$$ is an ancestor of node $$V$$ or node $$V$$ is an ancestor of node $$U$$, the above Swap operation is not performed.
  • Find the sum of node values present in the subtree rooted at node $$X$$.
  • If the Swap operation is performed, then redo this operation. That is, swap the subtree with $$U$$ as the root node and subtree with $$V$$ as the root node.

Determine the required answer for $$Q$$ queries.

Note

• Assume 1-based indexing.
• A node $$u$$ is said to be an ancestor of node $$v$$ if node $$u$$ lies on a simple path between the root and node $$v$$.
• Here, Redo means re-doing the operation performed.

Input format

• The first line contains a single integer $$T$$ that denotes the number of test cases.
• For each test case:
  • The first line contains an integer $$N$$.
  • The second line contains $$N$$ space-separated integers denoting array $$A$$.
  • The next $$N - 1$$ line contains two space-separated integers $$u v$$ denoting an edge between node $$u$$ and $$v$$.
  • The next line contains an integer $$Q$$.
  • The next $$Q$$ lines contain three space-separated integers $$U V X$$ denoting the query.

Output format

For each test case, print $$Q$$ space-separated integers denoting the sum of node values present in the subtree rooted at node $$X$$ after the swap operation is performed. Print the output for each test case in a new line.
