Assume we have a fully implemented singly linked list (similar to the one we learned in the course):1. Implement a method called mid () which returns the element stored in the middle node asfollows:o if the list has odd number of nodes, then output should be the middle element. e.g. if givenlist is 1->2->3->4->5, then return 3.• If there are even nodes, then there would be two middle nodes; return second middleelement. For example, if given list is 1->2->3->4->5->6, then return 4.o If list is empty, return null.Assume you can't use the get(index) method and you have to implement the mid() methodfrom scratch.2. What is the time complexity of your approach in terms of Big-O?public class MyLinkedList{private Node head, tail;private int size;... //assume standard methods are implemented here (e.g. isEmpty(), add(), remove(), etc)mplement the mid() method hereprivate class Node{E element;Node next;public Node(E element) (this.elementelement;}

As per company rules we are only supposed to answer one question, so kindly post the other question…

Write a method subsets that uses recursive backtracking to find every possible sub-list of a given list. A sub-list of a list L contains 0 or more of L's elements. Your method should accept a List of strings as its parameter and print every sub-list that could be created from elements of that list, one per line. For example, suppose a variable called list stores the following elements: [Janet, Robert, Morgan, Char]The call of subsets(list); would produce output such as the following: [Janet, Robert, Morgan, Char][Janet, Robert, Morgan][Janet, Robert, Char][Janet, Robert][Janet, Morgan, Char][Janet, Morgan][Janet, Char][Janet][Robert, Morgan, Char][Robert, Morgan][Robert, Char][Robert][Morgan, Char][Morgan][Char][][3:07 AM]The order in which you show the sub-lists does not matter, but the order of the elements of each sub-list DOES matter (Note: this requirement is a limitation of Practice-It testing code.

This is in c++ Given the MileageTrackerNode class, complete main() to insert nodes into a linked list (using the InsertAfter() function). The first user-input value is the number of nodes in the linked list. Use the PrintNodeData() function to print the entire linked list. Don't print the dummy head node. Example input : 3 2.2 7/2/18 3.2 7/7/18 4.5 7/16/18 output: 2.2, 7/2/18 3.2, 7/7/18 4.5, 7/16/18 main.cpp: #include "MileageTrackerNode.h"#include <string>#include <iostream>using namespace std; int main (int argc, char* argv[]) {// References for MileageTrackerNode objectsMileageTrackerNode* headNode;MileageTrackerNode* currNode;MileageTrackerNode* lastNode; double miles;string date;int i; // Front of nodes listheadNode = new MileageTrackerNode();lastNode = headNode; // TODO: Read in the number of nodes // TODO: For the read in number of nodes, read// in data and insert into the linked list // TODO: Call the PrintNodeData() method// to print the entire linked list //…
In python two possible ways please
The linked list provided below:2 > 3 > 1 > 7 > 5 > 18 > NULLHere the > symbol means a pointer.Write a complete Python program which deletes the third last node of thelist and returns to you the list as below2 > 3 > 1 > 5 > 18 > NULLThe third last node (with a value 7) has now been dislodged from the list.Here are the few things to consider :(a) We do NOT know the length of the list.(b) Your solution should be in O(n) time and O(1) space having madejust a single pass through the list.
Create a nested class called DoubleNode that allows you to create doubly-linked lists with each node containing a reference to the item before it and the item after it (or null if neither of those items exist). Then implement static methods for the following operations: insert before a given node, insert after a given node, remove a given node, remove from a given node, insert at the beginning, insert at the end, remove from a given node, and remove a given node.

java In this assignment you will swap a position in an array list with another. swap() gets 3 arguments, an Arraylist, a position, and another position to swap with. Example swap(["one","two","three"],0,2) returns:["three","two","one"] public static ArrayList<String> swap(ArrayList<String> list,int pos1,int pos2) public static void main(String[] args) { Scanner in = new Scanner(System.in); int size = in.nextInt(); int pos1 = in.nextInt(); int pos2 = in.nextInt(); ArrayList<String> list = new ArrayList<>(); for(int i=0; i < size; i++) { list.add(in.next()); } System.out.println(swap(list, pos1, pos2)); } }

JAVA: Write a recursive method named threeSum that accepts a list of integers and prints all combinations of three integers in the list that sum to 0. For example, if given the list [-1, 0, 1, 2, -1, -4], print the following lines of output: [-1, 0, 1] [-1, 2, -1] [0, 1, -1] You may print the lines of output in any order. The elements in each three-element sublist should appear in the same relative order that they appeared in the original list. Do not print duplicate lists; if the same exact sublist can be made in multiple ways, print it only once. If there are no combinations of three elements that sum to 0, print no output. The list passed to your method must be back to its original state at the end of the call. Either do not modify it, or if you modify it, fully undo your modifications before the method returns. Constraints: Do not declare any global variables. You can use any data structures you like, and your code can contain loops, but the overall algorithm must be recursive and…
Implement a function findMixedCase in Python that: accepts a single argument, a list of words, and returns the index of the first mixed case word in the list, if one exists, (a word is mixed case if it contains both upper and lower case letters), and returns -1 if the all words are either upper or lower case. sample: >> findMixedCase( ['Hello','how','are','you'] ) # 'Hello' is mixed case0
