2. Implement a main method that does the following: Use Java

(a) Creates a binary search tree to hold sports scores as data for a sport of your own choice

(b) Adds between 5 and 8 scores to the tree using standard tree operations Try insert

(c) Choose one of the tree traversals, preorder or postorder, and use it to print out all elements of the tree

(d) Delete one score from the tree using standard tree operations (suppose the score was found to be illegitimate) (e) Use an iterator to get a list for an inorder traversal for the tree (so that you can process each element from the tree), and print out a message about the sports score, including the sport and other informative information you can come up wit

The following flow chart is a bubble sort. Write the code for this sort. Make sure you display each pass and comparison. Include comments.

i'm working on this assignment where we must simulate a bank account. I am having a few issues. The first issue is that for menu option 1 i am struggling to make the program so that I can add the name and balance of the account all at once. For example I would type "mike 350" and it would update the dictionary with a new account and balance, right now i have to open the account then deposit a balance separately using two different menu functions. The second issue i am having is that every account name in the dictionary has the same balance, I need to have each person have a separate balance. The third and last issue I am having is with menu option #6, i am not sure how to list the account names and balances with a number of each account to the left, the professor wants the output to look like this for option 6

No Customer Name   Balance

I have made it this far.

All along we have been discussing processing similar kind of data in a MapReduce job. In other words lots of data of same kind. But sometimes, you have to process two different kinds of data sets together, join them and produce a joined output. This is called joins. We take joins for granted in RDBMS, but it takes an effort to implement in MapReduce. Research various Join techniques/algorithms available for MapReduce. In your opinion, what are the pros and cons of the various MapReduce join options. Please keep it to your own words rater than paraphrasing sentences from websites.

Create a program called DualPivotQuickSort.java that implements the QuickSort algorithm using Yaroslavskiy’s algorithm. The program should be able to do the following: accepts one command line parameter. The parameter specifies the path to a text file containing the integers to be sorted. The structure of the file is as follows: There will be multiple lines in the file (number of lines unknown). Each line will contain multiple integers, separated by a single whitespace. reads the integers from the text file in part a into an array of integers. sort the integers in descending order using DualPivotQuickSort, and then prints out a sorted version of these integers on a single line, separated by white spaces. The implementation should follow the given the pseudo code/algorithm description.

Create a MIPS assembly program to calculate x^y using a recursive subprogram. You may assume that y is not negative.

1. What is the function of a replacement algorithm?  Do you need a replacement algorithm for direct mapping?  
2. Define the two write policies in about ten sentences total. Discuss the relative merits of the policies.  
3. Describe a simple way of implementing an LRU replacement algorithm in a 4-way set associative cache.
4. What is the impact of the design decision of line size on hit ratio?  Discuss the various approaches of cache coherency in a multiprocessor system (in about 10 sentences).  Discuss the relative merits of unified vs. split (code/data) cache design.    

SpriteKit is Apple’s built in 2D Gaming API, but there are others out there. What other libraries exist for developing 2D games? What are the advantages or disadvantages with using SpriteKit vs these other libraries?

The result of subtracting the following two signed binary numbers on an eight bit machine is

JAVA PROGRAMMING Write a program that ask the user for a number then prints the cube of the number. The program should be called CubeNumbers. Use a value returning method with parameter, call the method myCube.

Step 2: using text editor (WordPad) to create a web page with the following content (you may cut-and-paste):

-----------------------------------------------------------------------------------

Just a screenshoot of the output

Book-O-Rama Catalog Search

Book-O-Rama Catalog Search

    Choose Search Type:

         Author      Title      ISBN    

    Enter Search Term:

-------------------------------------------------------------------------------------

Then save above document to the local directory (C:\temp) and make sure that you saved it in the plain text format (in the “Save as type” popup window, choose “Text Document (*.txt)), name your file “firstpage.txt”.

Step 3: test your web page

You can test your page by doing the following:

1. change the file extension to html. Thus, you should have a file firstpage.html.

2. create a sub director named “firstwebsite” in the web server’s root directory. Your web root may be different from mine. In my machine, the XAMPP is installed at C drive. Thus, the web root will be:

C:\xampp\htdocs\

At the end of this step, the directory structure will be:

C:\xampp\hpdocs\firstwebsite\

3. copy the newly created file “firstpage.html” to the directory shown in the previous line.

4. fire up a web browser and type the following to the URL:

http:\\localhost\firstwebsite\firstpage.html
