2. Each student at Middlesex County College takes a different number of courses, so the registrar has decided to use linear linked lists to store each student's class schedule and an array to represent the entire student body. A portion of this data structure is shown below: ID link $|||||| 1/1234 Sec cr 3 CSC1621 →HISHO 24 2357 CSC2364 3/ 2 These data show that the first student (ID: 1111) is taking section 1 of CSC162 for 3 credits and section 2 of HIS101 for 4 credits; the second student is not enrolled; the third student is enrolled in CSC236 section 4 for 3 credits. Write a class for this data structure. Provide methods for creating the original array, inserting a student's initial class schedule, adding a course, and dropping a course. Include a menu-driven program that uses the class.

Specifically, we utilized the "single row" method to display a single row from a database. Scalar function or vector function? Which is preferable?
A very long line: What data structure or structures would you use to maintain a very long queue of records, each having an id (some sort of string). You need to be able to find the first item in O(1) time, add to the end in O(1), and remove items in O(1) time, given some id (not index), from anywhere in the line. Additionally, you need to be able to find an item in line in O(1) time and see what items are near it (in front of or in back of) in O(1), possibly more (each is O(1) time). Explain what is stored in each Data Structure (“record (with id possibly)”, “pointers to ______”).

Attach File Browse My Computer QUESTION 2 - use Eclipse to create a project. create a new class containing a main function. - Create a function describing the bubble sort to sort a LinkedList of Integers in the decreasing order (from the largest number to the smallest number). The function should accept a LinkedList and returm a LinkedLlist. Add also statements to trace the progress of bubble sort to display the LinkedList contents after each exchange. The main function should contain at least two test examples of the bubble sort function that you have create on various ordered and random LinkedList of Integers. NB: Send only the Java file containing your work. If the program dose not compile, marks will be reduced. if the program dose not properly as described above, marks will be reduced.

Define the function print_trophic_class_summary(tli3_values) that accepts a list of trophic level index values and prints a summary outlining the number of lakes in each trophic classification, in order from highest trophic classification to lowest. See the examples for the required format. Notes: Your function must print the summary, not return it. In each state line, the initial number should be formatted with width 3. (Hint: :3 will be helpful) All possible states must be included in the output, even states with zero lakes. The following list will be helpful: ['Hypertrophic', 'Supertrophic', 'Eutrophic', 'Mesotrophic', 'Oligotrophic', 'Microtrophic', 'Ultra-microtrophic'] You must include and use one of your number_in_trophic_class functions (take your pick!), plus your trophic_class function. Basically, you can start with your answer to Question 5 or 6 and add your print_trophic_class_summary function definition after your previous definitions. For example: Test Result…

Case study: An event company asks you to design the data structure and program prototype for their running event system. The participant for the running event is expected to reach more than 1000 in various categories. You decided to use hashing function method to store the information for each participant's BIB number in the hash table. To begin the problem solving, suppose that 10 registered runners need to be stored in a hash table, HT, with a size of 13. The sample BIB number of the runners are: 101, 102, 103, 104, 107, 111, 121, 217, 157, and 185. Furthermore, you set the hash function to determine the index of the participant in the HT as: hash (BIB) = BIB % table size (or 13) However, if the hash index given by hash(BIB) is already occupied (collision), the linear probing hash function will be used as: hash (BIB) = (Hash (BIB)+1) % 17 and, further collision with hash function: hash (BIB) = (Hash(BIB)+2) % 17 or, hash(BIB) = (Hash (BIB) + n) % 17, where n is probe increment.
