Maximizing Binary Matrix Score With Row And Column Flipping
Maximize binary matrix score by flipping rows & columns to ensure most significant bits are 1 and maximize remaining bits. Calculate final score by interpreting each row as a binary number.
861. Score After Flipping Matrix Difficulty: Medium Topics: Array, Greedy, Bit Manipulation, Matrix You are given an m x n binary matrix grid. A move consists of choosing any row or column and toggling each value in that row or column (i.e., changing all 0's to 1's, and all 1's to 0's). Every row of the matrix is interpreted as a binary number, and the score of the matrix is the sum of these numbers. Return the highest possible score after making any number of moves (including zero moves). Example 1: Input: grid = [[0,0,1,1],[1,0,1,0],[1,1,0,0]] Output: 39 Explanation: 0b1111 + 0b1001 + 0b11...
