2 * [2482] Difference Between Ones and Zeros in Row and Column
3 *
4 * You are given a 0-indexed m x n binary matrix grid.
5 * A 0-indexed m x n difference matrix diff is created with the following procedure:
6 * 
7 * 	Let the number of ones in the i^th row be onesRowi.
8 * 	Let the number of ones in the j^th column be onesColj.
9 * 	Let the number of zeros in the i^th row be zerosRowi.
10 * 	Let the number of zeros in the j^th column be zerosColj.
11 * 	diff[i][j] = onesRowi + onesColj - zerosRowi - zerosColj
12 * 
13 * Return the difference matrix diff.
14 *

17 * Input: grid = [[0,1,1],[1,0,1],[0,0,1]]
18 * Output: [[0,0,4],[0,0,4],[-2,-2,2]]
19 * Explanation:
20 * - diff[0][0] = onesRow0 + onesCol0 - zerosRow0 - zerosCol0 = 2 + 1 - 1 - 2 = 0 
21 * - diff[0][1] = onesRow0 + onesCol1 - zerosRow0 - zerosCol1 = 2 + 1 - 1 - 2 = 0 
22 * - diff[0][2] = onesRow0 + onesCol2 - zerosRow0 - zerosCol2 = 2 + 3 - 1 - 0 = 4 
23 * - diff[1][0] = onesRow1 + onesCol0 - zerosRow1 - zerosCol0 = 2 + 1 - 1 - 2 = 0 
24 * - diff[1][1] = onesRow1 + onesCol1 - zerosRow1 - zerosCol1 = 2 + 1 - 1 - 2 = 0 
25 * - diff[1][2] = onesRow1 + onesCol2 - zerosRow1 - zerosCol2 = 2 + 3 - 1 - 0 = 4 
26 * - diff[2][0] = onesRow2 + onesCol0 - zerosRow2 - zerosCol0 = 1 + 1 - 2 - 2 = -2
27 * - diff[2][1] = onesRow2 + onesCol1 - zerosRow2 - zerosCol1 = 1 + 1 - 2 - 2 = -2
28 * - diff[2][2] = onesRow2 + onesCol2 - zerosRow2 - zerosCol2 = 1 + 3 - 2 - 0 = 2

32 * Input: grid = [[1,1,1],[1,1,1]]
33 * Output: [[5,5,5],[5,5,5]]
34 * Explanation:
