Row with Maximum Number of 1s
Given a binary matrix, identify the row that has the maximum number of 1s. The initial approach involves applying binary search on every row with a time complexity of O(m log n). An optimized solution starts from the top-right corner of the matrix. If the current value is 1, move left; if 0, move down. Keep track of the row whenever moving left. The final time complexity is O(m + n) and space complexity is O(1).
