My code is attached below

public class Solution {
    
    public int MaximumWealth(int[][] accounts) {
    
             int min = -1;
                int row = accounts.GetLength(0);
               
                int[] sum = new int[row];
                for(int i=0;i<row;i++)
                {
    
                  for(int j=0;j<accounts[i].Length;j++)
                    {
    
                        sum[i] += accounts[i][j];
                    }
                }

                for(int i=0;i<row;i++)
                {
    
                    if(sum[i]>min)
                    {
    
                        min = sum[i];
                    }
                }

                return min;
    }
}
