This is the easy version of the problem. The only differences between the two versions of this problem are the constraints on $$$n$$$ and the time limit. You can make hacks only if all versions of the problem are solved.
You are given two arrays $$$a$$$ and $$$b$$$ of length $$$n$$$.
You can perform the following operation some (possibly zero) times:
Determine if you can make array $$$a$$$ equal to array $$$b$$$.
Each test contains multiple test cases. The first line contains an 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 a single integer $$$n$$$ ($$$1 \le n \le 1000$$$) — the length of the arrays.
The second line contains $$$n$$$ integers $$$a_1, a_2, \ldots, a_n$$$ ($$$1 \le a_i \le n$$$) — the elements of array $$$a$$$.
The third line contains $$$n$$$ integers $$$b_1, b_2, \ldots, b_n$$$ ($$$1 \le b_i \le n$$$) — the elements of array $$$b$$$.
It is guaranteed that the sum of $$$n^2$$$ over all test cases does not exceed $$$10^6$$$.
For each test case, output "YES" (without quotes) if you can make $$$a$$$ into $$$b$$$ using any number of operations, 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).

YES NO YES NO NO
In the first test case, we can achieve array $$$b$$$ by applying a single operation: $$$(l,r)=(2,3)$$$.
In the second test case, it can be shown we cannot achieve array $$$b$$$ in any amount of operations.
In the third test case, we can achieve array $$$b$$$ by applying two operations: $$$(l,r)=(2,5)$$$. followed by $$$(l,r)=(1,3)$$$.
In the fourth and fifth test cases, it can be shown we cannot achieve array $$$b$$$ in any amount of operations.
