Al and Bill are arguing about the performance of their sorting algorithms. Al claims that his O(N log N)-time algorithm is always faster than Bill's O(N2)-time algo- rithm. To settle the issue, they implement and run the two algorithms on many randomly generated data sets. To Al's dismay, they find that if N 〈 1000 the O(N2)- time algorithm actually runs faster, and only when N 〉 1000 the 0(N logN)-time (10 pts.) one is better. Explain why the above scenario is possible

Analyze the following code. int x = 1; while (0 < x) & & (x < 100) system.out.println(x++); a. the loop runs forever. b. the code does not compile because the loop body is not in the braces. c. the code does not compile because (0 < x) & & (x < 100) is not enclosed in a pair of parentheses. d. the numbers 1 to 99 are displayed. e. the numbers 2 to 100 are displayed.

7.23 main lab 7 - online shopping cart background this main lab extends the earlier prep lab "online shopping cart part 1". (you should save this as a separate project from the earlier prep lab). you will create an on-line shopping cart like you might use for your on-line purchases. the goal is to become comfortable with setting up classes and using objects. requirements this lab can be done individually or as pair programming. expanded itemtopurchase class (15 points) extend the itemtopurchase class as follows. we will not do unit testing in this lab so we will not be giving you the names of the member functions. create good ones on your own. create a parameterized constructor to assign item name, item description, item price, and item quantity (default values of "none" for name and description, and 0 for price and quantity). additional public member functions set an item description get an item description print the cost of an item - outputs the item name followed by the quantity, price, and subtotal (see example) print the description of an item - outputs the item name and description (see example) additional private data members a string for the description of the item. example output of the function which prints the cost of an item: bottled water 10 @ $1.50 = $15.00 example output of the function which prints the item description:
