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.
