Write down the insertBefore method which inserts a new element in the list before the node containing the given element. The method takes as parameters a dummy headed doubly linked circular list, the element existing in the list and new element to be added. public void insertBefore (Node head, Object elem, Object newElement) { //to do OR def insertBefore (head, elem, newElement) : pass insertBefore (head, 3, 50) Sample Input Sample Output ০x 1 2 स 3 हे 40 O x21 2 2 2 50 2 3 2 4 0

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:

Given the source code of linked List, answer the below questions(image): A. Fill out the method printList that print all the values of the linkedList: Draw the linked list. public void printList() { } // End of print method B. Write the lines to insert 10 at the end of the linked list. You must draw the final linked List. Notice that you can’t use second or third nodes. Feel free to define a new node. Assume you have only a head node C. Write the lines to delete node 2. You must draw the final linked list. Notice that you can’t use second or third node. Feel free to define a new node. Assume you have only a head node
Write a function in C++ that takes a pointer to an array as one parameter, and the length of the array as the second parameter. The function shall calculate the longest contiguous streak of odd numbers present in the array. You do not need to handle negative length arrays. Use Example: int. main(){ int array[] = {1,2,3,4,5,7,9}; std::cout << "Number Odd: << numOdd(array, 7); std::cout << std::endl; } Output: 3
