- You develop a Python application for your school. You need to read and write data to a text file. If the file does not exist, it must be created. If the file has content, the content must be removed. Which code should you use? Group of answer choices open(“local_data”, “r”) open(“local_data”, “w+”) open(“local_data”, “r+”) D. open(“local_data”, “w”)Python: I am trying to write a simple GUI based program with two input fields “Directory/filename” and “word” next to each other and one output text field below. Using recursion the program should go through all the files and folders searching for the entered word. If a match is found the path to the file should be printed in the text field + the content of line the word is found in . It should also print how many folders and files has been searched and how many times the word was found. Any ideas?Course:Data Structure and Algorithms Kindly do this correct as soon as possible: I am providing the a menu base programs in java for address book by using doubly LinkedList and arrayList in a menu which are following: 1.Enter 1 for using Doubly linkedList 2.Enter 2 for using arrayList YOU have to use File handling which create person.text file like this: Perform these steps while application is loading up.

- Suppose you wish to make an application that traverses a computer's filesystem and an- alyzes the amount of space (in megabytes) used by all of the various files and directories. Your application must store the following information: • The amount of space used by each individual file. • The total amount of space used by the contents of each directory (folder). For each directory, you need to store the total amount of space used by all files in that directory and all of the files in all of its sub-directories (sub-folders), sub-sub-directories, and so forth. For example: if the only files in the filesystem are: /Users/Mark/Documents/exam.tex (0.014 Mb) /Users/Mark/Documetns/exam.pdf (0.3Mb Mb) /Users/Mark/piratesong.mp4 (2.9 Mb) Then the stored size for /Users/Mark/Documents would be 0.314 Mb (sum of the sizes of the two files in the Documents directory), and the stored size for the directories /Users/Mark, /Users, and / would be 3.214 (sum of the sizes of all three files because they…java program that Creates an INDEXCEPTION value of the unique vowels and unique consonants that the name that was given to you can create.Input: A string of the name that was GIVEN TO YOU. CASE SENSITIVE.Process1: For every unique vowel of a name, you need to get the first index of that vowel from the original string. 2: For each vowel index you get from step 1, you will get the unique consonant from that position. if the index is out of scope of the consonant array, ignore that vowel index. 3: For each unique consonant that you get from step 2, you need to get the first index of that consonant from the original string. 4: Get the value of indexception by adding all index you get from step 3.OutputTO BE DISPLAYED- 2 lists that consists of unique vowels and unique consonants- The vowel, the vowel index, the consonant, the consonant indexFINAL OUTPUT- The total indexception value of the name that was given to you.IN C++ Write a program that represents a playlist on a video streaming service. Each video has a title and total minutes. The user should be able to do the following with the playlist: Add video to list Remove video from list Display list in alphabetical order by title Exit playlist Your driver file will need a storage object that can handle any amount of videos. You will also need to provide a menu that shows and performs the various options above. The menu should continue to display until the user selects the "Exit playlist" option. A description of each menu option is listed below: Add video to list Prompts the user for a video title and total minutes Then your code stores the video onto the storage object of your choice Remove video from list Prompts the user for a video title Then your code removes that video from your storage object Display list in alphabetical order Displays the video's title and total minutes for each video in your storage object.

Business…With your knowledge in file systems write a javaprograms the can be used to: Rename a file in a directoryUsing visual studio 2019 and using c# programming Create a WPF app that will take a value n from the user, representing a side of a square matrix. Your program will generate an n x n char matrix. The chars’ values are randomly generated. This matrix will be printed into a text file. Suppose the data that is contained in the text file is as follows. s d k w e a e r e q j g e u c n t q a d s w a s f w t n The user must be able to provide a string to your app and your app will verify that the string exists in the generated matrix. For example, suppose the user wants to see if qwerty is in the matrix. The user provides qwerty to your system, and they are informed it doesn’t exist in there! What if the user provides aereq? Well, the user will be informed the string exists. I will only be testing in the vertical (going down) and horizontal (going right to left) directions. Please explain your algorithms for this part
- This question comes from the textbook:Starting out with Visual C# 5th Edition - Chapter 14 Programming Problem 2 Create an application that reads the contents of two text files and uses LINQ extension methods to perform the following: • It should display a list of all the unique words contained in both files.• It should display a list of the words that appear in both files.• It should display a list of the words that appear in the first file but not the second.• It should display a list of the words that appear in the second file but not the first.• It should display a list of the words that appear in either the first or second file but not both. Hint: Use set operations to perform these analyses. Also, see Chapter 8 for a discussion of string tokenizing.Design an application that can be used to read DVD titles from a text file.
