Problem

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

To flip the image horizontally, reverse each row.

To invert the image, change each 0 to 1 and each 1 to 0.

Return the transformed image.

Examples

flipImage([[1,1,0],[1,0,1],[0,0,0]])
// [[1,0,0],[0,1,0],[1,1,1]]
/* Why?
- Flip each row: 
    * [1,1,0] -> [0,1,1]
    * [1,0,1] -> [1,0,1]
    * [0,0,0] -> [0,0,0]
- Invert the image: 
    * [0,1,1] -> [1,0,0]
    * [1,0,1] -> [0,1,0]
    * [0,0,0] -> [1,1,1]
So, the final modified image is: [[1,0,0],[0,1,0],[1,1,1]] */

flipImage([[1,1,0,0],[1,0,0,1],[0,1,1,1],[1,0,1,0]])
// [[1,1,0,0],[0,1,1,0],[0,0,0,1],[1,0,1,0]]
/* Why?
- Flip each row: 
    * [1,1,0,0] -> [0,0,1,1]
    * [1,0,0,1] -> [1,0,0,1]
    * [0,1,1,1] -> [1,1,1,0]
    * [1,0,1,0] -> [0,1,0,1]
- Invert the image: 
    * [0,0,1,1] -> [1,1,0,0]
    * [1,0,0,1] -> [0,1,1,0]
    * [1,1,1,0] -> [0,0,0,1]
    * [0,1,0,1] -> [1,0,1,0]
So, the final modified image is: [[1,1,0,0],[0,1,1,0],[0,0,0,1],[1,0,1,0]] */
