A different version of bubble sort keeps track of where the last exchange occurred, and on the next pass, it will not go past this point. If the last change was made in the swap of locations i and i + 1, the next pass will not look at any elements past location i. a. Write this new version of bubble sort.
b. Write a short paragraph that explains exactly why this new version of bubble sort will work.
c. Does this new version of bubble sort change the worst-case analysis?

What are "open-loop" and "closed-loop" systems

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.
