You are given two points $(p_x,p_y)$ and $(q_x,q_y)$ on a Euclidean plane.

翻译中…

You start at the starting point $(p_x,p_y)$ and will perform $n$ operations. In the $i$-th operation, you must choose any point such that the Euclidean distance$^{\text{∗}}$ between your current position and the point is exactly $a_i$, and then move to that point.

翻译中…

Determine whether it is possible to reach the terminal point $(q_x,q_y)$ after performing all operations.

翻译中…

$^{\text{∗}}$The Euclidean distance between $(x_1, y_1)$ and $(x_2, y_2)$ is $\sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}$

Input

翻译中…

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

翻译中…

The first line of each test case contains a single integer $n$ ($1\leq n \leq 10^3$) — the length of the sequence $a$.

翻译中…

The second line of each test case contains four integers $p_x,p_y,q_x,q_y$ ($1\leq p_x,p_y,q_x,q_y\leq 10^7$) — the coordinates of the starting point and terminal point.

翻译中…

The third line of each test case contains $n$ integers $a_1,a_2,\ldots,a_n$ ($1 \le a_i \le 10^4$) — the distance to move in each operation.

翻译中…

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

Output

翻译中…

For each test case, output "Yes" if it is possible to reach the terminal point $(q_x,q_y)$ after all operations; otherwise, output "No".

翻译中…

You can output the answer in any case (upper or lower). For example, the strings "yEs", "yes", "Yes", and "YES" will be recognized as positive responses.

翻译中…

Note

翻译中…

Here is a picture that shows a possible movement of the first test case. The coordinates of point $r_1$ are $(3,1+\sqrt{5})$.

翻译中…

image The first test case.

翻译中…

Here is a picture that shows a possible movement of the second test case. The coordinates of point $r_1$ are $(1+\sqrt{3},0)$, and the coordinates of point $r_2$ are $\left(-\frac{(\sqrt{3}+4)(3\sqrt{3(149-24\sqrt{3})}-7\sqrt{3}-38)}{104},-\frac{\sqrt{3(1331-764\sqrt{3})}+12\sqrt{3}-27}{104}\right)$.

翻译中…

image The second test case.

翻译中…

For the third test case, it can be shown that there is no set of moves that satisfies all requirements.

翻译中…

Here is a picture that shows a possible movement of the fourth test case.

翻译中…

image The fourth test case.
