You are given a tree \(T\) with \(N\) nodes rooted at node 1. Each node has a value \(A[i]\) associated with it.

You are required to perform \(Q\) queries where each query is of type:

• \(1 \ u \ x\): Increment the value associated with node \(u\) by \(x\).
• \(2 \ p\): Find the shortest distance of any node from the root that has a value strictly greater than \(p\). If no such node exists, then print -1.

Note: There exists at least 1 query of type 2.

Input format

• The first line contains an integer \(T\) denoting the number of test cases.
• The first line of each test case contains an integer \(N\).
• The second line of each test case contains \(N\) space-separated integers denoting array \(A\).
• Next \(N - 1\) lines of each test case contain two space-separated integers denoting the edge.
• The next line of each test case contains an integer \(Q\) denoting the number of queries.
• Next \(Q\) lines of each test case contain queries.

Output format

For each test case, print the answer of queries of type \(2\) in a new line.
