- 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']Program Description: The project is a student management system which maintains student records in a simple text file. Your task is to write a program to save a list of students records in a FILE and then perform several operations on this FILE. Your program will ask user to choose the option from a menu. The 3 major function in menu are: ADD STUDENT FIND STUDENT PRINT LIST Exit How it Works The menu is handled by do while and switch statement. Sample output The Methods to be implemented are as follows: 1. ADDSTUDENT This method will add a new student to the file. It takes 3 parameters ( student name, id, and GPA). Your program must ask the user to enter the details of new students: Name, ID and GPA 2. FINDSTUDENT This method will search for a student with his/her id in the file. If the student is found it will print her/his record to the output. If the student is not found it will print “There is no record of this student in this system” 3. PRINTLIST This method will print all the…Using C++ how can I use Binary Search Tree (BST) to update a file.The code needs to be a menu-driven application that can: read a file and store the words and their count in BST store words that have at least 4 letters, ignore the rest there will be no words with ' (he's - for example will not be in the input file) print the words and their count in alphabetical order (A-Z) in a table format search for a word display the count and the word if found delete a word delete the word from the BST AND replace each occurrence of the word with a number of Xs equal to the length of the word; for example, delete word "camp", in the input file every occurrence of the word "camp" is replaced with XXXX use the search function you wrote for the search option to locate the word and delete it quit Also, how could I implement the BST as a linked list and how could I replace the words in the file with X's
- l JO 100 4G 2:02 AM @ 52% assignment_3 v2 AI and ML Assignment 3 Write a python program to cluster candidates into 2/3 groups. The program performs dimensionality reduction, then clustering of candidates based on top 2 PCs. The results are plotted to visually show the performance of candidates. The program performs the following tasks: Read input "pca cluster.csv" file. Use Panda library.

Remember that overtime it is hard for an OS to find disk space to cover the entire file so it usually splits these up into chunks across the physical hard drive and stores a sequential list of links together as a linked list. Write an algorithm for the above problem and analyse the efficiency of the algorithm.The python function first_words takes one parameter, fname, the name of a text file, and returns a list containing the first 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 ["apples", "bananas", "limes"] 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 of a for loop!), then L = line.split() creates a list of the words in the line.
- Computer Science using java The program has to evaluate arithmetic expressions using a BST for thatpurpose. The rules are the following:The program asks the user to enter an arithmetic expression in the infixformat. Then the program builds a BST for that expression. After buildingthe BST, a menu will be present to the user allowing him to: traverse the BST in inorder, traverse the BST in postorder, traverse the BST in preorder.Users will choose among the options present. The result will be thedisplay of the original arithmetic expression and the new one thatdepends on the option chosen. The program should repeat as long as theuser wants.In the attached file, you will find a function that creates a binary search tree of a given size and files that will randomly generate keys in the range [1,1000]. The value associated with each key can be passed to the function, default is 1. Complete the program by implementing the necessary code to perform the following tasks: Create a binary search tree of size 20, name it bst Print all keys in bst on a single line to save space Print the mimimum key in bst Print the smallest key larger than 500 in bst (if any) Print all keys in the range [100,300] in bst Print the tree height Import the modules first before doing this. from bst.binary_search_tree import TreeMapfrom AVLTreeMap import AVLTreeMapimport random def create(size, value = 1): bst = AVLTreeMap() # or just use AVLTreeMap() counter = 0 while counter<size: val = random.randint(1,1000) if not val in bst.keys(): bst[val] = value counter +=1 return bstC# language Write a program that creates a Queue or Stack (your choice) that represents a list of work orders. This program should use loop, allowing the user to push and pop items on the stack / queue. The program should also allow the user to print all the items in the stack / queue to the console.
- Al-Balqa Applied University Computer Science Department Programming with Java Assignment #2 Use the File class to complete the following tasks: Create (using Java code) the following tree of folders and files. (Let the folder "BAU" to be created in the Desktop). BAU Center Others Test.txt A1.docx Ask the user to enter a file name. Create a text file with the same name entered by the user inside the "Center" folder. (For example, if the user enters the word "IT", your code should create the file "IT.txt" inside the "Center" folder). Write a code that counts how many files exist in the "Center" folder.Using Dyanmic LL write a C++ program to do the following: Create a Dynamic LL Add anode: a) When the List is empty b) In the beginning of the List c) In the end of the List d) Somewhere between the beginning and the end of the List. e) Purge the LL The ADD algorithm is to determine where the new node to be placed in the List. The user is not be asked where the new node should be inserted. Delete a node: a) When the List is empty b) From the beginning of the List c) From the end of the List d) From somewhere between the beginning and the end of the List. The DELTE algorithm is to determine where the targeted node is placed in the List. The user is not be asked about the location of the targeted node. Search for a node and display its contents. The Search is done based on a key field from the node (i.e a name, or an ID) The Search algorithm is to locate the targeted node and to display it The user is not be asked about the location of the targeted node.…Program Description:in C language The project is a student management system which maintains student records in a simple text file.
