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.

PYTHON prov_records_per_date() takes a 2-D list (similar to the database) and an integer representing the province ID. This function returns another 2-D list, where each element of this list stores information in the following format. [ [day1, total number of patients (both icu and non-icu) in this provice reported in day1], [day2, total number of patients (both icu and non-icu) in this provice reported in day2], ... ] >>> results = prov_records_per_date(database, 35) >>> display_dict(result) >>> display_list(result) ['2022-01-31', 239] ['2022-02-05', 393] >>> results = prov_records_per_date(database, 10) >>> display_dict(result)['2022-02-02', 225] >>> results = prov_records_per_date(database, 81) >>> display_dict(result)No data in list

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: link Sec cr CSC16213 →HISHO 24 $||1|| 1/1234 2/2 357 CSC236/4 37 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. s 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.

List data_list contains integers read from input, representing a sequence of data values. For each index i of data_list from 1 through the second-to-last index: The element at index i is a drop if the element is less than both the preceding element and the following element. If the element at index i is a drop, then output 'Drop: ', followed by the preceding element, the current element, and the following element, separating each element by a space.

program9_1.pyThis assignment requires you to create a dictionary by reading the text file created for the Chapter 6 assignment. The dictionary should have player names for the keys. The value for each key must be a two-element list holding the player's goals and assists, respectively. See page 472! Start with an empty dictionary. Then, use a loop to cycle through the text file and add key-value pairs to the dictionary. Close the text file and process the dictionary to print the stats and determine the top scorer as before. In fact, much of the code used in program6_2.py can be copied and used for this program. Printing the stats for each player is the most challenging part of this program. To master this, refer to the examples in the zip file that can be downloaded from the "Dictionary values can be lists" link in the "Learn Here" part of this module. NOTE: you do not need to submit the text file. Submit just this program. The required output should be the same well-formatted table as…
