Question 1: SQL ---------------- Assume you have the following tables: Item +-------------+--------------+------+-----+----------------+ | Field | Type | Null | Key | Extra | +-------------+--------------+------+-----+----------------+ | itemID | int(11) | | PRI | auto_increment | | name | varchar(64) | | | | | description | varchar(128) | YES | | | | categoryID | int(11) | YES | | | +-------------+--------------+------+-----+----------------+ Category +-------------+--------------+------+-----+----------------+ | Field | Type | Null | Key | Extra | +-------------+--------------+------+-----+----------------+ | categoryID | int(11) | | PRI | auto_increment | | name | varchar(64) | | | | +-------------+--------------+------+-----+----------------+ ItemOrderMembership +-------------+--------------+------+-----+----------------+ | Field | Type | Null | Key | Extra | +-------------+--------------+------+-----+----------------+ | orderID | int(11) | | | | | itemID | int(11) | | | | +-------------+--------------+------+-----+----------------+ Write a query that will get me the item name and item category name for all items in orderID 12345. Please note that [login to view URL] may be NULL, and that the query should return item names even for those records where this is the case. Question 2: Python Programming ----------------------- A teacher gives a class of students an exam. He decides to grade the exam using the following method: * A score in the top 20% of all scores is an A. * A score in the next 20% of scores is a B. * A score in the next 20% of scores is a C. * A score in the next 20% of scores is a D. * A score in the bottom 20% of scores is an F. For example, if a class of 20 students has the following scores: 99, 92, 91, 91, 89, 85, 83, 82, 80, 79, 78, 78, 77, 76, 75, 74, 62, 55, 43, 20 The first four scores (99, 92, 91, 91) would be an A, scores 5 through 8 (89, 85, 83, 82) would be a B, scores 9 through 12 (80, 79, 78, 78) would be a C, scores 13 through 16 would be a D (77, 76, 75, 74) and scores 17 through 20 (62, 55, 43, 20) would be an F. Write a function that takes an arbitrary (possibly unsorted) score list of any length (not necessarily the list used as an example above) as a parameter, and returns a grade for each score. Note that since the list of scores can be of any length the number of scores may not necessarily be divisible by 5. Please make sure your function will handle those cases gracefully and consistently. ADDITIONAL REQUIREMENT: If there are two (or more) scores that are identical, then those identical numerical scores must always receive the same grade, even if that causes some grades to contain more scores than others. You may use any programming language you wish. Please make sure your code is syntactically valid and would produce an output that identifies which letter grade is received by each numerical score in the input list.

I am very proficient in java. I have 16 years java developing experience now, and have worked for more than 6 years. My work is online game developing, and mainly focus on server side, using java under linux environment. I used java to make many great projects, for example, I made the tools which can convert java files into c++ scripts, of course garbage collection included, this job is very similar to a compiler, and is very complex. I also made our own mobile game using java, I can show you the demo of client, if you like. I have a very good review on Freelancer.com, I never miss a project once I accept the job, you can check my review. Trust me, please let expert help you. Besides, I am very proficient in c++ also, hope I can help you.
