g Reversing an array is a common task. One approach copies to a second array in reverse, then copies the second array back to the first. However, to save space, reversing an array without using a second array is sometimes preferable. Write a function that reads in an integer representing the length of the array. Then read in and reverse the given array, without using a second array. If the original array's values are 2 5 9 7, the array after reversing is 7 9 5 2. Write a method to reverse the input array and call the method in the main. Note: The first item in the input is the length of the input array. The rest of the items in the input are the elements stored inside of the input array. Hints: Use this approach: Swap the first and last elements, then swap the second and second-to-last elements, etc. Stop when you reach the middle; else, you'll reverse the vector twice, ending with the original order. Think about the case when the number of elements is even, and when odd. Make sure your code handles both cases.
