翻译中…

Vika came to her favorite cosmetics store "Golden Pear". She noticed that the prices of $n$ items have changed since her last visit.

翻译中…

She decided to analyze how much the prices have changed and calculated the difference between the old and new prices for each of the $n$ items.

翻译中…

Vika enjoyed calculating the price differences and decided to continue this process.

翻译中…

Let the old prices be represented as an array of non-negative integers $a$, and the new prices as an array of non-negative integers $b$. Both arrays have the same length $n$.

翻译中…

In one operation, Vika constructs a new array $c$ according to the following principle: $c_i = |a_i - b_i|$. Then, array $c$ renamed into array $b$, and array $b$ renamed into array $a$ at the same time, after which Vika repeats the operation with them.

翻译中…

For example, if $a = [1, 2, 3, 4, 5, 6, 7]$; $b = [7, 6, 5, 4, 3, 2, 1]$, then $c = [6, 4, 2, 0, 2, 4, 6]$. Then, $a = [7, 6, 5, 4, 3, 2, 1]$; $b = [6, 4, 2, 0, 2, 4, 6]$.

翻译中…

Vika decided to call a pair of arrays $a$, $b$ dull if after some number of such operations all elements of array $a$ become zeros.

翻译中…

Output "YES" if the original pair of arrays is dull, and "NO" otherwise.

Input

翻译中…

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

翻译中…

The first line of each test case contains a single integer $n$ ($1 \le n \le 10^5$) — the number of items whose prices have changed.

翻译中…

The second line contains $n$ integers $a_1, a_2, \ldots, a_n$ ($0 \le a_i \le 10^9$) — the old prices of the items.

翻译中…

The third line contains $n$ integers $b_1, b_2, \ldots, b_n$ ($0 \le b_i \le 10^9$) — the new prices of the items.

翻译中…

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

翻译中…

Output

翻译中…

For each test case, output "YES" if the pair of price arrays is dull, and "NO" otherwise.

翻译中…

You can output each letter in any case (lowercase or uppercase). For example, the strings "yEs", "yes", "Yes", and "YES" will be accepted as a positive answer.

翻译中…

Note

翻译中…

In the first test case, the array $a$ is initially zero.

翻译中…

In the second test case, after the first operation $a = [1, 2, 3], b = [0, 0, 0]$. After the second operation $a = [0, 0, 0], b = [1, 2, 3]$.

翻译中…

In the third test case, it can be shown that the array $a$ will never become zero.
