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.

Develop the program incrementally: a) start by reading and displaying each line of the input file to make sure you are reading the data set correctly. b) use the split string method to extract information from each line into a list. print the list to prove that this step is working correctly. d) convert the exam scores to type int and calculate the student’s average. display those items to prove this step is working correctly. e) create a tuple containing the six items for each student (name, exam scores, exam mean). display the tuples to prove this step is working correctly. (optionally, you may want to have the exam scores in a list so your tuple is (name, scores_list, f) append each tuple to a list. display the list to prove this step is working correctly. g) use the sort list method to re-order the tuples in the list. display the list to prove this step is working correctly. h) use a for statement to display the contents of the list as a table (with appropriate formatting). i) use a for statement to calculate the average of all scores on exam #1, then display the results. note that you could have calculated this average within the first loop, but we are explicitly requiring you to do this calculation by looping though your list of tuples. j) add the logic to calculate the average of all scores on exam #2, then display the results.
