Write a computer program that prompts the user for a number, creates an array for that number of random integers, and then usees the bubble sort to order the array. The program should print out the array prior to the call to the sorting algorithm and afterward. You can write the program in either Java, C++, C#, or whatever language you are most comfortable in. Do Not use an API from the language library. Write the program to perform the sort.

Repeat 1 but use selection sort this time. Again, write out the program for the selection sort. DO not use the language library.

1. 1 and 2 are primarily intended to make sure that your algorithms work.

Once you are convinced your programs to work, do the following

1. Write a computer program that prompts the user for one number, n for the number of items in the array to sort, and create and sort 1000 different arrays of this size timing the run to get an average time to sort an array of this size. Then do the following:Initiate a variable running_time to 0Create a for loop that iterates 1000 times.In the body of the loop,Create an array of n random integersGet the time and set this to start-time (notice the sort is started after each array is built. You want to time the srt process only). You will have to figure out what the appropriate command is in the programming language you are using to find the time (Important: Do not start the timer until after the array is created).Use bubble sort to sort the arrayGet the time and set this to end-time Subtract start-time from end-time and add the result to total_timeOnce the program has run, noteThe number of items sortedThe average running time for each array (total_time/1000)Repeat the process using 500, 2500 and 5000 as the size of the array.

Repeat 3 using selection sort.

You now have 6 data points ( the averages from the three array sizes for the two sort algorithms) Create a spreadsheet showing the results of 3 and 4 and create a graph to graphically represent the information. Show both sort algorithms on the same graph for comparison.

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. Use your knowledge of complexity analysis to explain your results.

The report. In the report, say which machine you ran the experiments on (type of processor, RAM, etc). Explain your experiment and why you feel you received the results you observed.

Khan Corporation is a midsize, privately owned, industrial instrument manufacturer supplying precision equipment to manufacturers in the Midwest. The corporation is 10 years old and uses an integrated ERP system. The administrative offices are located in a downtown building and the production, shipping, and receiving departments are housed in a renovated warehouse a few blocks away. Customers place orders on the company’s website, by fax, or by telephone. All sales are on credit, FOB destination. During the past year sales have increased dramatically, but 15% of credit sales have had to written off as uncollectible, including several large online orders to first-time customers who denied ordering or receiving the merchandise. Customer orders are picked and sent to the warehouse, where they are placed near the loading dock in alphabetical sequence by customer name. The loading dock is used both for outgoing shipments to customers and to receive incoming deliveries. There are ten to twenty incoming deliveries every day, from a variety of sources.

The increased volume of sales has resulted in a number of errors in which customers were sent the wrong items. There have also been some delays in shipping because items that supposedly were in stock could not be found in the warehouse. Although a perpetual inventory is maintained, there has not been a physical count of inventory for two years. When an item is missing, the warehouse staff writes the information down in log book. Once a week, the warehouse staff uses the log book to update the inventory records. The system is configured to prepare the sales invoice only after shipping employees enter the actual quantities sent to a customer, thereby ensuring that customers are billed only for items actually sent and not for anything on back order.

Questions:

a. Identify at least three weaknesses in Khan Corporation’s revenue cycle activities.

b. Describe the problem resulting from each weakness.

c. Recommend control procedures that should be added to the system to correct the weakness.

Question 2:

What are the advantages of the REA data model over the traditional AIS model?

Question 3:

Identify and discuss two methods of production planning.
