Description:
HI~~
I am looking for someone to help me with my Java code writing. Basically, what you have to do is to answer all the questions that I am going to have, help me when I get stuck and help me with debug.
I need someone able to communicate with me at least once per day or even more often. Thank you very much.
Below is just a brief decirption about my assignment
[1]
Prove that a binary tree with N nodes has N+1 null pointers.
[2]
The getNext function is used in the Network Management protocol SNMP. Given a Binary Search tree T holding integers, write a function getNext(T, n) that returns the smallest integer in T that is bigger than n. If there is no such integer, return n.
A sequence of calls to getNext can be used to traverse the tree, by feeding the result of the last search as a parameter to the new search.
[3]
Write a program that takes a tree whose nodes hold a single character and prints the tree as we would draw it. The Left offspring of a node should be below and to the left. The Right offspring should be below and to the right. For example, the tree ca.b..ed... would be printed as:
c
a e
b d
[4]
Given the pre-order and the in-order traversal of a tree it is possible to reconstruct the tree. Write a program that accepts two strings on the command line representing the in-order and pre-order representation of a binary tree. Echo print the two strings, then construct the binary tree they represent, and use the PrintLevel routine to display the tree's shape. The tree might not be a sorted binary tree.
[5] Huffman Encoding
This project uses Priority Queues, Binary Trees, and Bit Manipulations to provide a useful facility: file compression. You will implement Huffman encoding to compress a text file. Your program will take two parameter: a file name and the word "compress" or "decompress". Given the input
% huffman mytext.txt compress
it will produce the file mytext.txt.huf, whose contents have been compressed using Huffman encoding. Given the input
% huffman yourtext.huf decompress
it will produce the decompressed file yourtext.
Deliverables:
1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done.
2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request.
3) Complete ownership and distribution copyrights to all work purchased.
4) I need to work be done by deadline
5) able to respond to my email within 24 hours
Platform:
Java JDK 1.31
Must be 100% finished and received by buyer on:
Nov 16, 2002 11:59:59 PM EDT
Deadline legal notes: All times are expressed in the time zone of the site EDT (UT - 5). If the buyer omitted a time, then the deadline is 11:59:59 PM EDT on the indicated date.
Special Conditions / Other:
must be able to respond to me within a day
Remember that contacting the other party outside of the site (by email, phone, etc.) on all business projects < $500 (before the buyer's money is escrowed) is a violation of both the software buyer and seller agreements.
We monitor all site activity for such violations and can instantly expel transgressers on the spot, so we thank you in advance for your cooperation.
If you notice a violation please help out the site and report it. Thanks for your help.

Hi,
I am an experienced developer and am well-versed with Java.
Will help you with any problems you face at Java, will help in debugging and also write snippets of code if you need.
Will ensure that you understand the concepts clearly.
I will be available on msn or yahoo to answer any questions that you might have.
