- Create a program that stores the names of the user's friends in a list. The program should allow a user to add friends to the list, remove friends from the list, and display the entire list of friends. A menu should be created that displays those options like so: 1 - View all 2 - Add Friend 3 - Remove Friend 4 - Exit The program should continue in a loop until the user selects exit. Hint: Use a function for each menu selection.Adding Students to a Club Create an application that displays a list of student names in a ListBox. Use a second empty ListBox to represent the members of a student club. Use a button labeled Addto copy member names from the general list to the club list. Use a button labeled Remove to remove a student from the club list. Keep a running count of the number of names in the club list. The application should perform the following error-checking:• Do not permit the same person’s name to be added twice.• Avoid throwing an exception if the user clicks the Add button before having selected a student name.• Avoid a runtime error if the user clicks the Remove selected member button, without having selected a member name In "Starting out with visual basic 8th edition programming challenge 5"GirlNames.txt This file contains a list of the 200 most popular names given to girls born in the United States from the year 2000 through 2009. BoyNames.txt This file contains a list of the 200 most popular names given to boys born in the United States from the year 2000 through 2009.

The list should initially contain all zeros (0). The algorithm for entering a grade is similar to: Find the appropriate position for the grade so that all grades are still in order from highest to lowest. Insert the grade Make certain that length of list remains the same The algorithm for deleting a grade is similar to: Find the element containing the grade to delete. If list empty tell user they can’ delete and if grade doesn’t exist, inform user no grade has been found. Use del function.

- Javascript question. Please solve with JavaScript NOT jQueryBuild a word list sorter with browser LocalStorage. How it works: A user will enter a word into an input or textarea and press submit. When clicking the submit button, the value of the intput/textarea should be added as a bullet point on a <ul> list below the intput/textarea. When added, the displayed list is re-sorted to include the new word and displayed again immediately. Requirements: Sort lexically in increasing order from top to bottom Use document.queryselector and event listeners to accomplish the list add word functionality Save word list in localStorage so that data persist on browser refresh Add a delete functionality to your list Please solve with JavaScript NOT jQueryUSE JAVA CODE Represent the features of a basic application using the linked list data structure (menu type). The minimum requirement is that the representation of data must be a list of lists but you may further create another list within the inner list. For instance, the menus of IntelliJ IDEA have different headings (File, Edit, View, Navigate, ...) and under each heading are menu options. Show the CRUD basics (create, read, update, and delete). Some options may have sub-options. In this case, there are 3 levels of nested lists. The outer most list will be the menu headings and under each heading will contain a list of options. An option, in turn, can have a list ofsub-options.The function last_words in python takes one parameter, fname, the name of a text file, and returns a list containing the last word from each line of the file. For example, if the file contents are: apples are red bananas are yellow limes are green then the list ["red", "yellow", "green"] should be returned. NOTE: You may assume the file will contain no blank lines. BIG HINT: If line is a string representing a line of text (inside a for loop!), then L = line.split() creates a list of the words in the line. For example: Test Result L = last_words("wordlist1.txt") print(L) ['happy', 'sad', 'angsty', 'euphoric', 'maudlin']
