using namespace std;


void diamond(int n) {
    int x = 1;
    for (int i=1; i<=n; i++) {
        for (int j=0; j<n-i; j++) {
            cout << "  ";
        }
        for (int j=0; j<i-1; j++) {
            cout << setw(2) << x++ << "  ";
        }
        cout << setw(2) << x++ << endl;
    }
    for (int i=n-1; i>0; i--) {
        for (int j=0; j<n-i; j++) {
            cout << "  ";
        }
        for (int j=0; j<i-1; j++) {
            cout << setw(2) << x++ << "  ";
        }
        cout << setw(2) << x++ << endl;
    }
}

int main() {    
    diamond(5);
    return 0;
