Part 2 Create a class called InsertionSort that implements SortAnalysis in a file named InsertionSort.java and use it to do the following: a) Describe a way of arranging elements of an array of length n such that the running time would be a worst-case for your InsertionSort algorithm. b) Write a program to determine the size n of the array that gives a running time of 1000 milliseconds. (Similar to (a) in Part 1.) c) Create a worst-case array as described in (a) for 100 A????1equally spaced sizesA????1 between 1 and the size determined in part (b); and compute the running time of your algorithm on these arrays. d) Plot the results of (b) on a graph alongside a plot of the analytical well-known worst-case running time of insertion sort and a best fit polynomial curve of degree 2. e) Create a pdf file that shows the plots from (d) and explain the differences you see in these plots. f) Repeat (b) through (e) except use random data for your analysis instead of worst-case data. Be sure to also explain in the pdf reasons for differences between worse case data and random data.
