AT_abc463_a.16:9

There is an image with a width of $X$ pixels and a height of $Y$ pixels. Determine whether the ratio of the width to the height is $16$ to $9$, that is, whether $X:Y=16:9$.

有一张图像，其宽度为 $X$ 像素，高度为 $Y$ 像素。判断该图像的宽高比是否为 $16:9$，即是否满足 $X:Y=16:9$。

The input is given from Standard Input in the following format:

$X$ $Y$

输入从标准输入给出，格式如下：

$X$ $Y$

If the ratio of the width to the height is $16$ to $9$, output Yes; otherwise, output No.

如果宽与高的比值为 $16$ 比 $9$，则输出 Yes；否则输出 No。

Sample 1 Explanation:
For an image with a width of $800$ pixels and a height of $450$ pixels, the ratio of the width to the height is $16$ to $9$.

Sample 2 Explanation:
For an image with a width of $234$ pixels and a height of $108$ pixels, the ratio of the width to the height is not $16$ to $9$.

Sample 3 Explanation:
For an image with a width of $108$ pixels and a height of $192$ pixels, the ratio of the width to the height is not $16$ to $9$.

Constraints

• $1 \leq X \leq 1000$
• $1 \leq Y \leq 1000$
• All input values are integers.

样例 1 解释：
对于一张宽度为 $800$ 像素、高度为 $450$ 像素的图像，其宽高比为 $16:9$。

样例 2 解释：
对于一张宽度为 $234$ 像素、高度为 $108$ 像素的图像，其宽高比不是 $16:9$。

样例 3 解释：
对于一张宽度为 $108$ 像素、高度为 $192$ 像素的图像，其宽高比不是 $16:9$。

约束条件

• $1 \leq X \leq 1000$
• $1 \leq Y \leq 1000$
• 所有输入值均为整数。
