Oner is a jungler — a role where you hunt monsters in a jungle. Given the number of trees he sees in a jungle, it's no surprise that he is addicted to tree query problems. You are given a tree of (n) vertices, rooted at vertex (1). Each vertex either contains a monster or does not. You want to find the minimum integer (k) such that there exist (k) paths that satisfy the following conditions: Each path must start at the root (vertex (1)). Every vertex with a monster must be included in at least one of these paths. A vertex is considered included in a path if it is one of the path's vertices, including its endpoints. To make this problem more challenging, you must also answer (q) queries. For each query, you are given a vertex (v). For each vertex (w) in the subtree of (v), its status is inverted — the one containing a monster starts to not contain one, and the one not containing a monster starts to contain one. After each query, you must solve the original problem again with the updated status. Note that queries are cumulative , so the effects of each query carry on to future queries. Each test contains multiple test cases. The first line contains the number of test cases (t) ((1 \le t \le 20\,000)). The description of the test cases follows. The first line contains a single integer (n) ((2 \le n \le 250\,000)) — the number of vertices in the tree. The next line contains (n) integers (a_1, a_2, \ldots, a_n) ((a_i \in \{0, 1\})), representing the initial status. If (a_i = 1), vertex (i) contains a monster; if (a_i = 0), it does not. The next (n-1) lines each contain two integers (u) and (v) ((1 \le u, v \le n, u \ne v)), describing an edge between vertices (u) and (v). It is guaranteed that these edges form a tree. The next line contains a single integer (q) ((0 \le q \le 250\,000)) — the number of queries. The next (q) lines each contain a single
