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:

#include
#include
using namespace std;

int main() {
vector countDown(0);
int newSize = 0;
int i = 0;

newSize = 3;

STUDENT CODE

for (i = 0; i < newSize; ++i) {
cout << countDown. at(i) << " ";
}
cout << "Go!" << endl;

return 0;
}
