Write a program that first reads in the name of an input file and then reads the input file using the file.readlines() method. The input file contains an unsorted list of number of seasons followed by the corresponding TV show. Your program should put the contents of the input file into a dictionary where the number of seasons are the keys, and a list of TV shows are the values (since multiple shows could have the same number of seasons). Sort the dictionary by key (least to greatest) and output the results to a file named output_keys.txt, separating multiple TV shows associated with the same key with a semicolon (;). Next, sort the dictionary by values (alphabetical order), and output the results to a file named output_titles.txt. Ex: If the input is: file1.txt and the contents of file1.txt are: 20 Gunsmoke 30 The Simpsons 10 Will & Grace 14 Dallas 20 Law & Order 12 Murder, She Wrote the file output_keys.txt should contain: 10: Will & Grace 12: Murder, She Wrote 14: Dallas…
/*TASK 5. Implement part 1 of the report. You need to read data from input.txt file, store it into array of items (called items) and write it in a formatted form to the output file. Code, debug and present it in the best possible format. Hint: It might be helpful to format the String coming from toString( ) method using String.format( ) method, which works similar to System.out.prinf. Hint2: You might have to close and delete existing output .doc or .txt file from its folder * public class YourUserName_hw7 { static Item [ ] items = new Item [200];//an array of Items static EdibleItem [ ] edibleItems;//an array of Edible Items static int countEdibleitems = 0;//count edible items static String pageHeader; //save the header //main( ) method runs the program public static void main(String[ ] args) throws FileNotFoundException { double sum = 0, average = 0; //Optional - create a new input file //CreateInput.createInputFile( );…
Write a complete program that prints out the list of files in the current directory, along with their file sizes and last modified datetime stamps. Any sub-directories are ignored. At the end, print the total file size. It accepts two optional command-line arguments: Sort field (single sort key only) “name" for filename, "size" for file size, 1 "date" for last modified datetime stamp, default is “name". "asc" for ascending, "desc" for descending, 2 Sort order default is “asc". A sample execution of the program with both command line arguments provided is shown below. $ python q3a.py date desc Filename Size Last Modified fileSorter.py / 1461 / Sat Jan 30 01:40:48 2021 optimized_fib.py / 273 / Fri Jan 29 10:53:45 2021 tic-tac-toe-bot-master.zip / 37180 / Thu Jan 28 15:12:03 2021 tictactoe.py / 8157 / Thu Jan 28 14:59:45 2021 getComputerMove.py / 1131 / Thu Jan 28 14:55:22 2021 Total file size: 48203 Research how you access the file system using the functions in the os module.

Java code: The program should ask the users for input and output files. Question: Write a code that compares Strassen’s Algorithms and ordinary multiplication. Include error handling. The output should compare the two algorithms (same output = True or false), each algorithm output should be included, and determine the number of matrix multiplication for each algorithm. Also, what' time and space complexity. Thank you!

Write a program that reads movie data from a CSV (comma separated values) file and output the data in a formatted table. The program first reads the name of the CSV file from the user. The program then reads the CSV file and outputs the contents according to the following requirements: Each row contains the title, rating, and all showtimes of a unique movie. A space is placed before and after each vertical separator ('|') in each row. Column 1 displays the movie titles and is left justified with a minimum of 44 characters. If the movie title has more than 44 characters, output the first 44 characters only. Column 2 displays the movie ratings and is right justified with a minimum of 5 characters. Column 3 displays all the showtimes of the same movie, separated by a space. Each row of the CSV file contains the showtime, title, and rating of a movie. Assume data of the same movie are grouped in consecutive rows. Hints: Use the find() function to find the index of a comma in each row of…
Make use of a random number generator to generate a list of 500 three-digit numbers. Create a sequential list FILE of the 500 numbers. Artificially implement storage blocks on the sequential list with every block containing a maximum of 10 numbers only. Open an index INDX over the sequential list FILE which records the highest key in each storage block and the address of the storage block. Implement Indexed Sequential search to look for keys K in FILE. Compare the number of comparisons made by the search with that of the sequential search for the same set of keys.Extend the implementation to include an index over the index INDX.
I am trying to read a CSV file and then store it into an ArrayList. For each row, I'm trying to create a new Country class instance and add it to the list. However, it is giving me the following as the output: edu.uga.cs1302.quiz.Country@7c9bb6b8 edu.uga.cs1302.quiz.Country@441847 edu.uga.cs1302.quiz.Country@2621fba7 edu.uga.cs1302.quiz.Country@4fa6e7a1 edu.uga.cs1302.quiz.Country@6e29b69b edu.uga.cs1302.quiz.Country@4e0f0d39 edu.uga.cs1302.quiz.Country@67da3b9c edu.uga.cs1302.quiz.Country@1f394329 edu.uga.cs1302.quiz.Country@3c07b33b edu.uga.cs1302.quiz.Country@a570747 edu.uga.cs1302.quiz.Country@3ce7cb4a edu.uga.cs1302.quiz.Country@6912e7f4 edu.uga.cs1302.quiz.Country@680d0f86 edu.uga.cs1302.quiz.Country@5a5250ff edu.uga.cs1302.quiz.Country@58ed7d64 edu.uga.cs1302.quiz.Country@26be1cca edu.uga.cs1302.quiz.Country@26cf56a4 edu.uga.cs1302.quiz.Country@6ed22f2a edu.uga.cs1302.quiz.Country@5de769c9 edu.uga.cs1302.quiz.Country@b6966f3 edu.uga.cs1302.quiz.Country@574f6b4c…
Write a function that reads all the numbers from a file into an array. The file is already open and there is no bad data in the file. The data is one number per line and an unknown number of lines of data. The function should read data until either end of file is detected or the array is full. Prototype void readData( ifstream& iFile, double numbers[ ], int size, int& count); iFile - already open ifstream numbers[ ] - array to store data size - the size of the array. count - the number of values read and must be set by the function before returning.

def analyze_file (filename: str, pos_words: List [str], neg_words: List [str]) -> Given the name of a file, a list of positive words (all in lowercase), and a list of negative words (all in lowercase), return some interesting data about the file in a tuple, with the first item in the tuple being the positivity score of the contents of this file, and the rest of the item: being whatever else you end up analyzing. (Helper functions are highly encouraged here.) How to calculate positivity score: For every word that is pos itive in the file (based on the words in the list of positive words) add 1 to the score. For every negative word (based on the list of negative words), subtract 1 from the score. Any neutral words (those that do not appear in either list) do not affect the score in any way. pass
Q1. The last post didnt include the items in the database. Need a different function for the python program display_ticket below: def display_tickets():t = Texttable()tickets=cur.execute('''SELECT * FROM tickets''')for i in tickets:t.add_rows([['tid', 'actual_speed','posted_speed','age','violator_sex'],list(i)])print()print(t.draw())print() Q2. Also need a different function for the python program add_ticket below: def add_tickets():actual_speed=int(input("enter actual speed:"))posted_speed=int(input("enter posted speed:"))age=int(input("enter age:"))sex=input("Male or Female:")cur.execute('''INSERT INTO tickets(actual_speed,posted_speed,age,violator_sex) VALUES(?,?,?,?)''',(actual_speed,posted_speed,age,sex))con.commit() If you'd like to see what thousands of traffic tickets look like, check out this link: https://www.twincities.com/2017/08/11/we-analyzed-224915-minnesota-speeding-tickets-see-what-we-learned/
Write a complete program that sorts dword unsigned integer array in descending order. Assume that the user doesn’t enter more than 40 integers. You MUST use the template-1-2.asm Download template-1-2.asm and follow all the directions there. Note: you have to review 3 peer assignments. You can’t add any more procedures to the template. The procedures can’t use any global variables (variables that are inside .data segment). The caller of any procedures sends its argument through the stack. Inside any procedures, if you need to use a register, you have to preserve its original value. You can't use uses, pushad operators. The callee is in charge of cleaning the stack Sample run: Enter up to 40 unsigned dword integers. To end the array, enter 0. After each element press enter: 1 4 3 8 99 76 34 5 2 17 0 Initial array: 1 4 3 8 99 76 34 5 2 17 Array sorted in descending order: 99 76 34 17 8 5 4 3 2 1 template-1-2.asm include irvine32.inc ;…
