解法：

#include<iostream>
#include<vector>
using namespace std;
int arr[100][100];
int main() {int n, max = 0;cin >> n;vector<int> sum(n, 0);for (int i = 0; i < n; i++) {for (int j = 0; j < n; j++) {cin >> arr[i][j];sum[i] += arr[i][j];}if (max < sum[i]) max = sum[i];}cout << max << endl;for (int i = 0; i < n; i++) {if (sum[i] == max)cout << i;}return 0;
}
