Given a m x n matrix, if an element is 0, set its entire row and column to 0. Do it in-place. Example 1: Input: [ [1,1,1], [1,0,1], [1,1,1] ] Output: [ [1,0,1], [0,0,0], [1,0,1] ] Example 2: Input: [ [0,1,2,0], [3,4,5,2], [1,3,1,5]
var img = new Bitmap(100 , 100); for (int i = 0; i < img.Width; i++) { for (int j = 0; j < img.Height; j++) { var c = img.GetPixel(i,j); Console.WriteLine(c.A); //输出0,表示透明背景,同时R=G=B=0 //img.SetPixel(i, j, Color.FromArgb(255, 0, 0,
