339. Flipping an Image
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:Input: image = [[1,1,0],[1,0,1],[0,0,0]]Output: [[1,0,0],[0,1,0],[1,1,1]]
