+/**
+ * 832. Flipping an Image
+ * https://leetcode.com/problems/flipping-an-image/
+ * Difficulty: 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].
