#include<bits/stdc++.h>
using namespace std;
int main() {
int n;
cin >> n;
// write your code here......
//使用new来新建二维动态数组
int** arr = new int* [n];
for (int i = 0; i < n; i++)
arr[i] = new int[n];
for (int i = 0; i < n; i++) {
for (int j = 0; j < n; j++) {
arr[i][j] = i + j;
cout << arr[i][j] << " ";
}
cout << endl;
}
//释放内存空间
for (int i = 0; i < n; i++)
delete[] arr[i];
delete[] arr;
return 0;
}
