Resize vector countDown to have newSize elements. Populate the vector with integers {newSize, newSize - 1, …, 1}. Ex: If newSize = 3, then countDown = {3, 2, 1}, and the sample program outputs: 3 2 1 Go! #include #include using namespace std; int main() {    vector countDown(0);    int newSize;    unsigned int i;    cin >> newSize;    /* Your solution goes here  */    for (i = 0; i < countDown.size(); ++i) {       cout << countDown.at(i) << " ";    }    cout << "Go!" << endl;    return 0; }
