Doing a practice exam...
 12) Write three statements to print the first three elements of vector runTimes. Follow each with a newline. Ex: If runTime = {800, 775, 790, 805, 808}, print:
 800 775 790 
 #include 
 #include 
 using namespace std;
 int main() {
 vector runTimes(5);
 // Populate vector
 runTimes.at(0) = 800;
 runTimes.at(1) = 775;
 runTimes.at(2) = 790;
 runTimes.at(3) = 805;
 runTimes.at(4) = 808;
 /* Your solution goes here */
 return 0;
 }
 13) Write a for loop to print all NUM_VALS elements of vector courseGrades, following each with a space (including the last). Print forwards, then backwards. End with newline. Ex: If courseGrades = {7, 9, 11, 10}, print:
 7 9 11 10 10 11 9 7 
 Hint: Use two for loops. Second loop starts with i = NUM_VALS - 1.
 #include 
 #include 
 using namespace std;
 int main() {
 const int NUM_VALS = 4;
 vector courseGrades(
