Given a 2D integer matrix M representing the gray scale of an image, you need to design a smoother to make the gray scale of each cell becomes the average gray scale (rounding down) of all the 8 surrounding cells and itself. If a cell has less than 8…

661. 图片平滑器 包含整数的二维矩阵 M 表示一个图片的灰度.你需要设计一个平滑器来让每一个单元的灰度成为平均灰度 (向下舍入) ,平均灰度的计算是周围的8个单元和它本身的值求平均,如果周围的单元格不足八个,则尽可能多的利用它们. 示例 1: 输入: [[1,1,1], [1,0,1], [1,1,1]] 输出: [[0, 0, 0], [0, 0, 0], [0, 0, 0]] 解释: 对于点 (0,0), (0,2), (2,0), (2,2): 平均(3/4) = 平均(0.75) =…
