ACTIVITY

$4\mathrm{.}2\mathrm{.}3$: Printing vector elements with a for loop.

Write a for loop to print all NUM$\_$VALS elements of vector courseGrades, following each with a space $($includir 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 $=$ courseGrades.size$()-1($Notes$)$

Note: These activities may test code with different test values. This activity will perform two tests, both with a $($vector$=4$;
