At your networking event, there are $n$ deals waiting to happen.

Each deal needs exactly two people, and every person is waiting for exactly one deal. So there are $2n$ people in total, and each deal ID $1 \ldots n$ appears on exactly two people's badges.

For corporate reasons, the organisers place each person on a unique vertex in a tree with $2n$ vertices. Vertex $v$ hosts a person with badge $a_v$.

Deal $i$ is sealed if, when the event begins, the two people with badge $i$ are on adjacent vertices. Each sealed deal contributes $w_i$ to your earnings.

Before the event starts, you are allowed one reshuffle:

1. Choose any (potentially empty) set of edges such that no two chosen edges share a vertex (i.e., the edges form a matching).
2. For every chosen edge $(u, v)$, swap the people at vertices $u$ and $v$.

After reshuffling, what is the maximum you can earn from this event?

Input

Each test contains multiple test cases. The first line contains the number of test cases $t$ ($1 \le t \le 10^4$). The description of the test cases follows.

The first line of each test case contains a single integer $n$ ($1 \leq n \leq 10^5$).

The next line contains $n$ integers $w_1, w_2, \ldots, w_n$ ($0 \leq w_i \leq 10^5$), where $w_i$ denotes the profit from deal $i$.

The next line contains $2n$ integers $a_1, a_2, \ldots, a_{2n}$. It is guaranteed that each value $1, 2, \ldots, n$ appears exactly twice in $a$.

The next $2n-1$ lines each contain two integers $u$ and $v$ ($1 \leq u, v, \leq 2n, u \neq v$) — denoting that an edge connects nodes $u$ and $v$.

It is guaranteed that the sum of $n$ over all test cases does not exceed $10^5$.

Output

For each test case, output a single integer — the maximum total earning after a reshuffle.

Note

Test 1. Swap edges $(1,2)$ and $(3,4)$ (they don't share vertices). Then the two 1s become adjacent on edge $(2,3)$, earning $w_1=10$, which beats keeping the existing 2—2 adjacency worth 3.

Test 2. The tree is a star. Swapping $(1,2)$ moves badge 1 to the center, making it adjacent to the other 1, earning $w_1=8$.

Test 3. Swap $(1,2), (3,4), (5,6)$ to seal two deals at once: edge $(2,3)$ becomes 1—1 (gain 4) and edge $(4,5)$ becomes 3—3 (gain 7), total 11.
