Two Arrays

1000ms 262144K

Description:

You are given two arrays of integers $$$a_1, a_2, \ldots, a_n$$$ and $$$b_1, b_2, \ldots, b_n$$$.

Let's define a transformation of the array $$$a$$$:

  1. Choose any non-negative integer $$$k$$$ such that $$$0 \le k \le n$$$.
  2. Choose $$$k$$$ distinct array indices $$$1 \le i_1 < i_2 < \ldots < i_k \le n$$$.
  3. Add $$$1$$$ to each of $$$a_{i_1}, a_{i_2}, \ldots, a_{i_k}$$$, all other elements of array $$$a$$$ remain unchanged.
  4. Permute the elements of array $$$a$$$ in any order.

Is it possible to perform some transformation of the array $$$a$$$ exactly once, so that the resulting array is equal to $$$b$$$?

Input:

The first line contains a single integer $$$t$$$ ($$$1 \le t \le 100$$$) — the number of test cases. Descriptions of test cases follow.

The first line of each test case contains a single integer $$$n$$$ ($$$1 \le n \le 100$$$) — the size of arrays $$$a$$$ and $$$b$$$.

The second line of each test case contains $$$n$$$ integers $$$a_1, a_2, \ldots, a_n$$$ ($$$-100 \le a_i \le 100$$$).

The third line of each test case contains $$$n$$$ integers $$$b_1, b_2, \ldots, b_n$$$ ($$$-100 \le b_i \le 100$$$).

Output:

For each test case, print "YES" (without quotes) if it is possible to perform a transformation of the array $$$a$$$, so that the resulting array is equal to $$$b$$$. Print "NO" (without quotes) otherwise.

You can print each letter in any case (upper or lower).

Sample Input:

3
3
-1 1 0
0 0 2
1
0
2
5
1 2 3 4 5
1 2 3 4 5

Sample Output:

YES
NO
YES

Note:

In the first test case, we can make the following transformation:

  • Choose $$$k = 2$$$.
  • Choose $$$i_1 = 1$$$, $$$i_2 = 2$$$.
  • Add $$$1$$$ to $$$a_1$$$ and $$$a_2$$$. The resulting array is $$$[0, 2, 0]$$$.
  • Swap the elements on the second and third positions.

In the second test case there is no suitable transformation.

In the third test case we choose $$$k = 0$$$ and do not change the order of elements.
