In Java. We sort lists of integers into ascending order and compare the performance of three sorting algortihms in Java: InsertSort, MergeSort , Quicksort. We want to look at two aspects of performance. 1. How the performance varies as the size of the input increases or rate of the growth performance. 2. How the algorithms perform on special kinds of lists. Part 1. Create a list of random numbers Provide a routine for generating list of random numbers of arbitrary size whose items are randomly generated. To do so generate random numbers. The length of the list should be a parameter that can change to assess the running time of the various sorting algorithms. Part 2 . Create arrays Create a method to generate ascending and descending lists of integers. Write a method that generates ascending and descending lists of integers( consecutive integers is fine). Also write a method to generate lists which consists of a few items many times repeated. To do this use the random list generator from Part 1. but restrict the possible integers to 0-9. Part.3 Sort Methods-Create code for the three sorting methods InsertSort, MergeSort and QuickSort. Can copy from text or Java libraries or websites. Part.4 Timing Analysis -Perform timing analysis on the Three sorting algorithms on the different lists that were made in Task 1 and 2 . Find the running time of the program. You can use different approaches such as the following. You can run each sorting algorithms on the different lists of increasing lengths. A max. length of 5,000 to 10,000 should be appropriate though on a slower processor it may be too large. Experiment create about 10 lists of lengths evenly spaced up to the max. Record you timing results. This can be done by having the program write the results to a file or track and plot manually using excel or another program
