Solution: Flipping an Image

Explore how to flip and invert an n by n binary image matrix in-place using bitwise manipulation. Learn to apply XOR operations to reverse and invert matrix rows simultaneously, improving efficiency and mastering a common coding interview pattern.

Statement

Given that an image is represented by an (n×n)(n \times n) matrix containing 00s and 11s, flip and invert the image, and return the resultant image.

Horizontally flipping an image means that the mirror image of the matrix should be returned. Flipping [1,0,0][1, 0, 0] horizontally results in [0,0,1][0, 0, 1].

Inverting an image means that every 00 ...
