reverse$($arr: StaticArray$)->$ None:

Write a function that receives a StaticArray from a static$\_$array class and reverses the order of the elements in the

array. The reversal must be done $$in place$,$ meaning that the original input array will be

modified, and you may not create another array $($nor need to$).$ You may assume that the

input array will contain at least one element. You do not need to check for this condition.

For full credit, the function must be implemented with O$($N$)$ complexity
