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 1
1 1 0 1 0 1 0 0 0
Input
image = [[1,1,0],[1,0,1],[0,0,0]]Output
[[1,0,0],[0,1,0],[1,1,1]]First reverse each row to get [[0,1,1],[1,0,1],[0,0,0]], then invert the image to get [[1,0,0],[0,1,0],[1,1,1]].
Example 2
1 1 0 0 1 0 0 1 0 1 1 1 1 0 1 0
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]]First reverse each row to get [[0,0,1,1],[1,0,0,1],[1,1,1,0],[0,1,0,1]], then invert the image to get [[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.
