C. After you have accomplished the task in part a, you are given k more names to put in the list. How many comparisons are necessary? What is the average number of comparisons actually needed?
A. We can use bubble sort to accomplich this task. First we find the smallest name from n names and it requires n-1 comparisons; Second in the rest n-1 names we find the smallest name and it requires n-2 comparisons. And so on. Finally the total number of comparison is:
(n-1) + (n-2) + ... + 2 + 1 = n(n-1)/2
