题目描述

There is an array $a$ of length $n$ . You may perform the following operation any number of times:

- Choose two indices $l$ and $r$ where $1 \le l < r \le n$ and $a_l = a_r$ . Then, set $a[l \ldots r] = [a_{l+1}, a_{l+2}, \ldots, a_r, a_l]$ .

You are also given another array $b$ of length $n$ which is a permutation of $a$ . Determine whether it is possible to transform array $a$ into an array $b$ using the above operation some number of times.

输入格式

Each test contains multiple test cases. The first line contains a single integer $t$ ( $1 \leq t \leq 10^4$ ) — the number of test cases. The description of the test cases follows.

The first line of each test case contains an integer $n$ ( $1 \le n \le 2 \cdot 10 ^ 5$ ) — the length of array $a$ and $b$ .

The second line of each test case contains $n$ integers $a_1, a_2, \ldots, a_n$ ( $1 \le a_i \le n$ ) — elements of the array $a$ .

The third line of each test case contains $n$ integers $b_1, b_2, \ldots, b_n$ ( $1 \le b_i \le n$ ) — elements of the array $b$ .

It is guaranteed that $b$ is a permutation of $a$ .

It is guaranteed that the sum of $n$ over all test cases does not exceed $2 \cdot 10 ^ 5$

输出格式

For each test case, print "YES" (without quotes) if it is possible to transform array $a$ to $b$ , and "NO" (without quotes) otherwise.

You can output "YES" and "NO" in any case (for example, strings "yEs", "yes" and "Yes" will be recognized as a positive response).
