We have a two dimensional matrix A where each value is 0 or 1. A move consists of choosing any row or column, and toggling each value in that row or column: changing all 0s to 1s, and all 1s to 0s. After making any number of moves, every row of this matrix is interpreted as a binary number, and the score of the matrix is the sum of these numbers. Return the highest possible score. Example 1: Input: [[0,0,1,1],[1,0,1,0],[1,1,0,0]] Output: 39 Explanation: Toggled to [[1,1,1,1],[1,0,0,1],[1,1,1,1]]. 0b1111 + 0b1001 + 0b1111 = 15 + 9 + 15 = 39 Note: 1 <= A.length <= 20 1 <= A[0].length <= 20 A[i][j] is 0 or 1.
