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 $a$:
- Choose any non-negative integer
$k$such that$0 \le k \le n$. - Choose
$k$distinct array indices$1 \le i_1 \lt i_2 \lt \ldots \lt i_k \le n$. - Add
$1$to each of$a_{i_1}, a_{i_2}, \ldots, a_{i_k}$, all other elements of array$a$remain unchanged. - 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).
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.
