2 * [3240] Minimum Number of Flips to Make Binary Grid Palindromic II
3 *
4 * You are given an m x n binary matrix grid.
5 * A row or column is considered palindromic if its values read the same forward and backward.
6 * You can flip any number of cells in grid from 0 to 1, or from 1 to 0.
7 * Return the minimum number of cells that need to be flipped to make all rows and columns palindromic, and the total number of 1's in grid divisible by 4.
