int main() {
    int arr[50], n;
    cout << "Enter 50 integers: ";
    for (int i = 0; i < 50; ++i) {
        cin >> arr[i];
    }
    cout << "Enter a value for n: ";
    cin >> n;
    for (int i = 0; i < 50; ++i) {
        for (int j = 0; j < 50; ++j) {
            if (arr[i] == n * arr[j]) {
                cout << "(" << arr[i] << ", " << arr[j] << ")" << endl;
            }
        }
