Question 2: Linked List Implementation You are going to create and implement a new Linked List class. The Java Class name is "StringLinkedList". The Linked List class only stores 'string' data type. You should not change the name of your Java Class. Your program has to implement the following methods for the StringLinked List Class: 1. push(String e) - adds a string to the beginning of the list (discussed in class) 2. printList() prints the linked list starting from the head (discussed in class) 3. deleteAfter(String e) - deletes the string present after the given string input 'e'. 4. updateToLower() - changes the stored string values in the list to lowercase. 5. concatStr(int p1, int p2) - Retrieves the two strings at given node positions p1 and p2. The retrieved strings are joined as a single string. This new string is then pushed to the list using push() method.
Problem Description: Q1) Write a method public static void downsize (LinkedList employeeNames, int n) that removes every nth employee from a linked list. Q2) Write a method public static void reverse (LinkedList strings) that reverses the entries in a linked list.
java program java method: Write a method replace to be included in the class KWLinkedList (for doubly linked list) that accepts two parameters, searchItem and repItem of type E. The method searches for searchItem in the doubly linked list, if found then replace it with repItem and return true. If the searchItem is not found in the doubly linked list, then insert repItem at the end of the linked list and return false. Assume that the list is not empty. You can use ListIterator and its methods to search the searchItem in the list and replace it with repItem if found. Do not call any method of class KWLinkedList to add a new node at the end of the list. Method Heading: public boolean replace(E searchItem, E repItem) Example: searchItem: 15 repItem: 17 List (before method call): 9 10 15 20 4 5 6 List (after method call) : 9 10 17 20 4 5 6
PYTHON LAB: Inserting an integer in descending order (doubly-linked list) Given main.py and an IntNode class, complete the IntList class (a linked list of IntNodes) by writing the insert_in_descending_order() method to insert new IntNodes into the IntList in descending order. Ex. If the input is: 3 4 2 5 1 6 7 9 8 the output is: 9 8 7 6 5 4 3 2 1 _____________________________________________________________________________________ Main.py: from IntNode import IntNode from IntList import IntList if __name__ == "__main__": int_list = IntList() input_line = input() input_strings = input_line.split(' ') for num_string in input_strings: # Convert from string to integer num = int(num_string) # Insert into linked list in descending order new_node = IntNode(num) int_list.insert_in_descending_order(new_node) int_list.print_int_list() IntNode.py class IntNode: def __init__(self, initial_data, next = None,…
