    832 - Flipping an Image.

    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].

    Example 1:

    Input: image = [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: image = [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]

    Constraints:

    • n == image.length

    • n == image[i].length

    • 1 <= n <= 20

    • images[i][j] is either 0 or 1.
