Suppose that an engineer excitedly runs up to you and claims that they’ve that can sort n elements (e.g., numbers) in fewer than n steps. Give some thought as to why that’s simply not possible and politely explain.

Use the Problem-Solving Strategy discussed in section 6.5 (pages 374 to 382) in the Prelude to Programming book to address solving the problem that has been given. Use the section 6.5 (pages 374 to 382) as a guide to what your documentation should include. This portion should be completed in a Word Document not exceeding 3 pages. Discuss your approach to securing your code from invalid data. Create and document test data to ensure it is error-free.

Janet Lopez is establishing an investment portfolio that will include stock and bond funds. She has $720,000 to invest and she does not want the portfolio to include more than 65% stocks. The average annual return for the stock fund she plans to invest in is 18% whereas the average annual return for the bond fund is 6%. She further estimates that the most she could lose in a year in the stock fund is 22% whereas the most she could lose in the bond fund is 5%. To reduce her risk, she wants to limit her potential maximum losses to $100,000

Sale-Receipt: Write a java program that specifies four parallel one-dimensional arrays to  store the product name, quantity and cost-plus ItemTotal. Each array should be capable of holding a number of elements provided by user input. Using a for loop input values for length and width arrays. The entries in the area arrays should be the corresponding values for the product, which is to be used to calculate the costs as follows (thus, itemTotat[i] = quantity[i]* cost [i]) after data has been entered display the following receipt as output: Product Quantity Cost Total Banana 4 2.65 10.60 coke 1 9.18 9.18 Sub-Total 19.78 VAT(15%) 2.97 TOTAL N$ 22.75 ample Run1 Enter the number of products: 2 Enter product 1 name, Qty and Cost: Banana 4 2.65 Enter product 1 name, Qty and Cost: Coke 1 9.18 Output1: Product Quantity Cost Total Banana 4 2.65 10.60 coke 1 9.18 9.18 Sub-Total 19.78 VAT(15%) 2.97 TOTAL N$ 22.75
