Given an n x n binary matrix image, flip the image horizontally, then invert it, and return the resulting image.

\n\n

To flip an image horizontally means that each row of the image is reversed.

\n\n\n\n

To invert an image means that each 0 is replaced by 1, and each 1 is replaced by 0.

\n\n\n\n

 

\n

Example 1:

\n\n
\nInput: image = [[1,1,0],[1,0,1],[0,0,0]]\nOutput: [[1,0,0],[0,1,0],[1,1,1]]\nExplanation: First reverse each row: [[0,1,1],[1,0,1],[0,0,0]].\nThen, invert the image: [[1,0,0],[0,1,0],[1,1,1]]\n
\n\n

Example 2:

\n\n
\nInput: image = [[1,1,0,0],[1,0,0,1],[0,1,1,1],[1,0,1,0]]\nOutput: [[1,1,0,0],[0,1,1,0],[0,0,0,1],[1,0,1,0]]\nExplanation: First reverse each row: [[0,0,1,1],[1,0,0,1],[1,1,1,0],[0,1,0,1]].\nThen invert the image: [[1,1,0,0],[0,1,1,0],[0,0,0,1],[1,0,1,0]]\n

给定一个 n x n 的二进制矩阵 image ,先 水平 翻转图像,然后 反转 图像并返回 结果 。

\n\n

水平翻转图片就是将图片的每一行都进行翻转,即逆序。

\n\n\n\n

反转图片的意思是图片中的 0 全部被 1 替换, 1 全部被 0 替换。

\n\n\n\n

 

\n\n

示例 1:

\n\n
\n输入:image = [[1,1,0],[1,0,1],[0,0,0]]\n输出:[[1,0,0],[0,1,0],[1,1,1]]\n解释:首先翻转每一行: [[0,1,1],[1,0,1],[0,0,0]];\n     然后反转图片: [[1,0,0],[0,1,0],[1,1,1]]\n
\n\n

示例 2:

\n\n
\n输入:image = [[1,1,0,0],[1,0,0,1],[0,1,1,1],[1,0,1,0]]\n输出:[[1,1,0,0],[0,1,1,0],[0,0,0,1],[1,0,1,0]]\n解释:首先翻转每一行: [[0,0,1,1],[1,0,0,1],[1,1,1,0],[0,1,0,1]];\n     然后反转图片: [[1,1,0,0],[0,1,1,0],[0,0,0,1],[1,0,1,0]]\n
