Consider the Strassen's matrix multiplication algorithm (a divide and conquer approach). (1) Using traditional matrix product method, how many multiplications and additions do we need to multiply two 2x2 matrices? How about Strassen's method? (2)Write down the related recurrence equation, and give the asymptotic tight bound solution. (3)Suppose that we use a similar divide and conquer approach to compute this problem; divide nxn matrices into x- 2 2 submatrics the same way as Strassen's ,while in the "merge" part, there are m submatrix multiplications and a submatrix additions. Find the time complexity of this method.

Richardson Ski Racing (RSR) sells equipment needed for downhill ski racing. One of RSR's products is fencing used on downhill courses. The fence product comes in 150-foot rolls and sells for $215 per roll. However, RSR offers quantity discounts. The following table shows the price per roll depending on order size: Quantity Ordered From To Price per Roll 1 30 $215 31 60 $195 61 ཙཙ 120 $175 121 and up $155 Click on the datafile logo to reference the data. (a) Use the VLOOKUP function with the preceding pricing table to determine the total revenue from these orders. $ (b) Use the COUNTIF function to determine the number of orders in each price bin. From To Price per Roll Number of Orders 1 30 $215 31 60 $195 61 120 $175 121 and up $155 172 12

Chapter 16 How to manage transactions and locking Excercises using the My Guitar Shop Database Use Microsoft SQL Server Write a script that includes two SQL statements coded as a transaction to delete the row with a customer ID of 8 from the Customers table. To do this, you must first delete all addresses for that customer from the Addresses table. If these statements execute successfully, commit the changes. Otherwise, roll back the changes.

(1) Prompt the user for a title for data. Output the title. Ex: Enter a title for the data: Number of Novels Authored You entered: Number of Novels Authored (2) Prompt the user for the headers of two columns of a table. Output the column headers. Ex: Enter the column 1 header: Author name You entered: Author name Enter the column 2 header: Number of novels You entered: Number of novels (3) Prompt the user for data points. Data points must be in this format: string, int. Store the information before the comma into a string variable and the information after the comma into an integer. The user will enter -1 when they have finished entering data points. Output the data points. Store the string components of the data points in an ArrayList of strings. Store the integer components of the data points in a second ArrayList of integers. Ex: Enter a data point (-1 to stop input): Jane Austen, 6 Data string: Jane Austen Data integer: 6 (4) Perform error checking for the data point entries. If…
