- JAVA please Given main() in the ShoppingList class, define an insertAtEnd() method in the ItemNode class that adds an element to the end of a linked list. DO NOT print the dummy head node. Ex. if the input is: 4 Kale Lettuce Carrots Peanuts where 4 is the number of items to be inserted; Kale, Lettuce, Carrots, Peanuts are the names of the items to be added at the end of the list. The output is: Kale Lettuce Carrots Peanuts Code provided in the assignment ItemNode.java:• Do not add statements that call print, input , or open , or add an import statement. • Do not use any break or continue statements. We are imposing this restriction (and we have not even taught you these statements) because they are very easy to abuse, resulting in terrible, hard to read code. • Do not modify or add to the import statements provided in the starter code. import math from typing import List, TextIO # For simplicity, we'll use "Station" in our type contracts to indicate that # we mean a list containing station data. # You can read "Station" in a type contract as: List[int, str, float, float, int, int, int] 23 # where the values at each index represent the station data as described in the # handout on Quercus. # A set of constants, each representing a list index for station information.

Given the following linked list: LinkedList list = new LinkedList(); And this code: 1. list.add(1.5); 2. list.addFirst(11.3); 3. list.add(6.2); 4. list.add(3.4); 5. list.addLast(4.8); 6. list.add(7.4); 7. list.remove(1.5); 8. list.remove(3.4); 9. list.removeFirst); 10. System.out.println(list.getFirst(); Answer the following questions regarding the code: a) What is the list after line 6? b) What is the list after line 9? c) Line 10 gives what value?Given main.py and a PersonNode class, complete the PersonList class by writing find_first() and find_last() methods at the end of the PersonList.py file. The find_first() method should find the first occurrence of an age value in the linked list and return the corresponding node. Similarly, the find_last() method should find the last occurrence of the age value in the linked list and return the corresponding node. For both methods, if the age value is not found, None should be returned. The program will replace the name value of each found node with a new name. Ex. If the input is: Alex 23 Tom 41 Michelle 34 Vicky 23 -1 23 Connor 34 Michela main.py(can not edit) from PersonNode import PersonNodefrom PersonList import PersonList if __name__ == "__main__": person_list = PersonList() # Read input lines until encountering '-1' input_line = input() while input_line != '-1': split_input = input_line.split(' ') name = split_input[0] age =…Assign negativeCntr with the number of negative values in the linked list.

- To finish up the definition of the Node class, we need at least two constructor methods. We definitely want a default constructor that creates an emptyNode, with both the Element and Link members set to null. We also need aparameterized constructor that assigns data to the Element member and setsthe Link member to null.Write the code for the Node class:Create different book objects (at least 5 books) and store them in a LinkedList sorted bybook barcode value. Generate a unique random integer value for the barcode.o Iterate through the LinkedList and print out the books’ detailso Create a second LinkedList object containing a copy of the above LinkedList, but inreverse order.Below you're given a Node class and a LinkedList class. You will implement a method for the LinkedList class named "delete48in148". That is, whenever there is a sequence of nodes with values 1, 4, 8, we delete the 4 and 8. For exCample, Before: 1 -> 4 -> 8 LAfter: 1 Before: 7 -> 1 -> 4 -> 8 -> 9 -> 4 -> 8 After: 7 -> 1 -> 9 -> 4 -> 8 Before: 7 -> 1 -> 4 -> 8 -> 4 -> 8 -> 4 -> 8 -> 9 After: 7 -> 1 -> 9 Note from the above example that, after deleting one instance of 48, there may be new instances of 148 formed. You must delete ALL of them. Requirement: Your implementation must be ITERATIVE (i.e., using a loop). You must NOT use recursion. Recursive solutions will NOT be given marks. import ... # No other import is allowed
- Which of the following code segments can be used as a constructor for a node in a linked list. Each node contains a pointer to the next node called next and also has a String called data. O public node () { next = 0; } } public node () { next = "";} } O public node () { next = null; } } O public node () { next = new node(); }Given the following definition for a LinkedList: // LinkedList.h class LinkedList { public: LinkedList(); // TODO: Implement me void printEveryOther() const; private: struct Node { int data; Node* next; }; Node * head; }; // LinkedList.cpp #include "LinkedList.h" LinkedList::LinkedList() { head = nullptr; } Implement the function printEveryOther, which prints every other data value (i.e. those at the odd indices assuming 0-based indexing).Explain why the code below does not run when using the test driver shown in screen shot. i also included the LLNode class and collectioninterface interface public class LinkedCollection<T> implements CollectionInterface<T> { protected LLNode<T> head; // head of the linked list protected int numElements = 0; // number of elements in this collection // set by find method protected boolean found; // true if target found, else false protected LLNode<T> location; // node containing target, if found protected LLNode<T> previous; // node preceding location public LinkedCollection() { numElements = 0; head = null; } public boolean add(T element) // Adds element to this collection. { LLNode<T> newNode = new LLNode<>(element); newNode.setLink(head); head = newNode; numElements++; return true; } protected void find(T target) // Searches the collection for an…
