+Given a binary matrix A, we want to 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].
+
+Example 1:
+
+Input: [[1,1,0],[1,0,1],[0,0,0]]
+Output: [[1,0,0],[0,1,0],[1,1,1]]
+Explanation: First reverse each row: [[0,1,1],[1,0,1],[0,0,0]].
+Then, invert the image: [[1,0,0],[0,1,0],[1,1,1]]
+Example 2:
+
+Input: [[1,1,0,0],[1,0,0,1],[0,1,1,1],[1,0,1,0]]
+Output: [[1,1,0,0],[0,1,1,0],[0,0,0,1],[1,0,1,0]]
+Explanation: First reverse each row: [[0,0,1,1],[1,0,0,1],[1,1,1,0],[0,1,0,1]].
+Then invert the image: [[1,1,0,0],[0,1,1,0],[0,0,0,1],[1,0,1,0]]
+Notes:
+
+1 <= A.length = A[0].length <= 20
+0 <= A[i][j] <= 1
