Prompt: Given an n x n array that represents the pixels on an image. You want to get the same image that is rotated 90 degrees from right to left.

Goal: Return a n x n array that is rotated 90 degrees from right to left

Examples:

Solution: A 90 degrees rotation from right to left is the same thing as flipping all the pixels diagonally and flipping all the pixels horizontally.

Example:

x o o
o x o
o o x
The x’s will be the line where each side flips diagonally.

o x o
o x o
o x o
The x’s will be the line where each side flips vertically.
