Harvard University Java Code Refactoring Unit Test and UML Diagram Program
Your job is to (i) create a design for the additions, (ii) implement the additions, (iii) create unittests for the additions, and (iv) identify opportunities for class-implementation and class-inter-face refactoring, and (v) do some refactoring where appropriate. May the source be with you!Task1. Review the old specification (specification.pdf) in the docs directory. You will ab-solutely need to understand it and the code you are extending.2. Review the extension specification at the end of this document, which describes all the ex-tensions to be done.3. Design and implement the extensions using the best-practices we discussed in class.4. Provide a readable, professional looking UML diagram of the updated design. This should bea PDF file called design.pdf in the docs directory.5. For each new class that you implement, you must provide unit tests in the form of Junit5tests. You should design your classes and modify existing classes to facilitate the testing.6. In a file in the docs directory called refactoring.txt list all the class-implementationand class-interface refactoring that you will do and refactoring that you would recommend.7. Perform any class-implementation and class-interface refactoring that you promised to do.8. Bonus: Research the Factory pattern that is used to instantiate classes derived from the samesuperclass or interface. E.g., all the JSON values could instead implement a Value interfaceor be subclasses of an abstract Value class and be constructed by a new ValueFactory classinstead of Value. Implement the Factory pattern to improve the creation of Values in Value.Be sure to update the UML diagram and provide unit tests.

Georgia State Univ Big Data Python Generator Streaming Functions Python Coding Task
Please submit a zip file. The zipped file should contain three separate ipython notebook files ’1-generator.ipynb’, ’2-HOF.ipynb’, and ’3- generator-HOF.ipynb’ for the first, second and third problems respectively.Python’s Generators and Streaming.Compute the median age of the Citibike’s subscribed customers. You are required to read data line by line and are not allowed to store the entire data set in memory. Indeed, you should not have any containers (e.g. list, dictionary, DataFrame, etc.) with more than 100 elements in memory. You should use yield when you want to iterate over a sequence, but don’t want to store the entire sequence in memory as shown in the Codes/Lab3.What to submit:Turn in an ipython notebook with the plot of the histogram of customers age and print out a single number showing the median age of the subscribed customers.Python’s Higher Order Functions: This is how you can read the file and transform it to a list of lists. import pandas as pd
df = pd.read_csv("citibike.csv")
rows = df.values.tolist()
(a) Determine the number trips that gender 1 made, and that gender 2 made. We can do this by just counting the number of occurrences of ”1” and ”2” in the gender column (2pt): <Read file>
<YOUR HOF EXPRESSION>
# After this, you should get something like
# (37805, 7848)
(b) Count the number of trips per birth year using higher order functions (2pt): <Read file>
<YOUR HOF EXPRESSION>
# After this, you should get something like
# {"1900.0": 22, "1901.0": 1, "1910.0": 2, "1922.0": 4, ... "1995.0": 256,
"1996.0": 124, "1997.0": 94, "1998.0": 59, "1999.0": 17}
What to submit:Turn in an ipython notebook print out the results for problems (a) and (b)3. Extract the first ride of the day from a Citibike data stream. The first ride of the day is interpreted as the ride with the earliest starting time of a day. For the sample data, which is a week worth of citibike records, your program should only generate 7 items (one for each day).Streaming Computation: you are asked to complete the task using steaming computation methods. You can only iterate the data set once using yield as shown in Codes/Lab3. You can store a container (e.g. list, dictionary, DataFrame,etc.) with maximum 7 elements in memory. The data set has been sorted by the starting time.What to submit:Turn in an ipython notebook print out the birth years of the first riders each day for problem.

C++ Programming Array Fill, computer science homework help
Write a function called RandomArrayFill that inputs (i.e., takes a parameter) an integer array, and also that inputs (i.e., takes a parameter) an integer, which contains the size of the array. The function is then to write a random number, in the range [0, 100], to each element of the array. The function declaration of this function should look like so:void RandomArrayFill(int* array, int size);Now write a program that asks the user to input the size of an integer array. The program then needs to create an array of exactly this size. Next, the program must pass this created array to theRandomArrayFill function, so that a random number is assigned to each element of the array. After which, the program must output every array element to the console window. Your program output should look similar to this:Enter the size of an array to create: 6Creating array and filling it with random numbers... Array = {57, 23, 34, 66, 2, 96}Press any key to continueAfter you finish implementing the above function, rewrite it again, but this time using std::vector. The function declaration of this new function should look like so:void RandomArrayFill(std::vector& vec);
