    832 - Flipping an Image\. Easy Given an `n x n` binary matrix `image`, flip the image **horizontally** , then invert it, and return _the resulting image_. To flip an image horizontally means that each row of the image is reversed. * For example, flipping `[1,1,0]` horizontally results in `[0,1,1]`. To invert an image means that each `0` is replaced by `1`, and each `1` is replaced by `0`. * For example, inverting `[0,1,1]` results in `[1,0,0]`. **Example 1:** **Input:** image = \[\[1,1,0],[1,0,1],[0,0,0]] **Output:** [[1,0,0],[0,1,0],[1,1,1]] **Explanation:** First reverse each row: [[0,1,1],[1,0,1],[0,0,0]]. Then, invert the image: [[1,0,0],[0,1,0],[1,1,1]] **Example 2:** **Input:** image = \[\[1,1,0,0],[1,0,0,1],[0,1,1,1],[1,0,1,0]] **Output:** [[1,1,0,0],[0,1,1,0],[0,0,0,1],[1,0,1,0]] **Explanation:** First reverse each row: [[0,0,1,1],[1,0,0,1],[1,1,1,0],[0,1,0,1]]. Then invert the image: [[1,1,0,0],[0,1,1,0],[0,0,0,1],[1,0,1,0]] **Constraints:** * `n == image.length` * `n == image[i].length` * `1 <= n <= 20` * `images[i][j]` is either `0` or `1`.
