Solution: Flipping an Image

Explore how to flip and invert an image represented as a binary matrix by applying bitwise XOR operations. Understand both naive and optimized approaches to modify the matrix in place while analyzing their time and space complexities, to improve problem-solving skills in coding interviews.

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 ...
