Understanding the Row With Maximum Ones Problem
Let's break down this LeetCode problem and understand what makes it challenging in interview settings.
Problem Statement
Given a m x n binary matrix mat, find the 0-indexed position of the row that contains the maximum count of ones, and the number of ones in that row. In case there are multiple rows that have the maximum count of ones, the row with the smallest row number should be selected. Return an array containing the index of the row, and the number of ones in it.

Get real-time assistance for Row With Maximum Ones problems during coding interviews. Interview Coder provides instant solutions and explanations.
Examples
mat = [[0,1],[1,0]][0,1]Both rows have the same number of 1's. So we return the index of the smaller row, 0, and the maximum count of ones (1). So, the answer is [0,1].
mat = [[0,0,0],[0,1,1]][1,2]The row indexed 1 has the maximum count of ones (2). So we return its index, 1, and the count. So, the answer is [1,2].
mat = [[0,0],[1,1],[0,0]][1,2]The row indexed 1 has the maximum count of ones (2). So the answer is [1,2].
Constraints
m == mat.lengthn == mat[i].length1 <= m, n <= 100mat[i][j] is either 0 or 1.How Interview Coder Helps with Leetcode Problems
