Timing experiment


Write a computer program that prompts the user for a number, creates an array for that number of random integers, and then uses the sophisticated form of bubble sort to order the array. The program should print out the array prior to the call to the sorting algorithm and afterwards. You can write the program in either Java, C++, C#, or whatever language you are most comfortable in. Repeat 1 but use insertion sort this time. 1 and 2 are primarily intended to make sure that your algorithms work. Once you are convinced your programs work, do the following Write a computer program that prompts the user for two numbers, n for the number of items in the array to sort, and num_ifor a number of iterations. Then do the following: Initiate a variable running_time to 0 Create a for loop that iterates num_i times. In the body of the loop, Create an array of n random integers Get the time and set this to start-time. You will have to figure out what the appropriate command is in the programming language you are using to find them time Use sophisticated bubble sort to sort the array Get the time and set this to end-time Subtract end-time from start-time and add the result to running_time Once the program has run, note The number of items sorted The number of iterations The running time Repeat the process nine times, using 5, 25 and 50 as the size of the array, and 10, 100 and 1000 as the number of iterations. Repeat 3 using selection sort. Create a spreadsheet showing the results of 3 and 4 and create a graph to graphically represent the information Write a one page document explaining the results, bearing in mind that both algorithms have a complexity of O(n^2) and what you know about complexity analysis. Please submit: Program code for 1 and the three program runs Program code for 2 and the three program runs Program code used in 3 Program code used in 4 The spreadsheet created in 5 The report. In the report, say which machine you ran the experiments on (type of processor, RAM, etc). Attachments
