Answer 1

#include <iostream>

#include <vector>

using namespace std;

bool isMagicSquare(vector<vector<int>> arr) {

vector<int> sum;

for (int i = 0; i < arr.size(); ++i) {

 sum.push_back(0);

 sum.push_back(0);

 for (int j = 0; j < arr.size(); ++j) {

  sum[sum.size() - 1] += arr[i][j];

  sum[sum.size() - 2] += arr[j][i];

 }

}

sum.push_back(0);

sum.push_back(0);

for (int i = 0; i < arr.size(); ++i) {

 sum[sum.size() - 1] += arr[i][i];

 sum[sum.size() - 2] += arr[arr.size() - i - 1][i];

}

for (int i = 0; i < sum.size() - 1; ++i)

 if (sum[i] != sum[i + 1])

  return 0;

return 1;

}

int main() {

vector<vector<int>> arr =  

  { {17, 24, 1, 8, 15},

 {23, 5, 7, 14, 16},

 {4, 6, 13, 20, 22},

 {10, 12, 19, 21, 3},

 {11, 18, 25, 2, 9}, };

cout << isMagicSquare(arr);

}
