19. 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?
head 7. Answer the questions considering the figure above. The list that you see above is a doubly DNode{ public T value, public DNode next, public DNode prev ..} When this list was created, they forgot to link the prev field of the nodes. Write a method existing list. Your method will be in the DoublyLinkedList class, so it does not need to tak since you will have an access to head.
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
Java's LinkedList provides a method listlterator(int index) returning a Listlterator for a list. Declare a variable of LinkedList of integer numbers and write a fragment of Java code to compute and print the sum of the numbers on the list. Do not write code to insert elements to the list and assume that the list already has elements on it. You must only use an iterator obtained from the list (you can not use the get(int index) method) .
Examine the following code: ArrayList<String> list = new ArrayList<String>(10) ; list.add("A"); list.add("B"); list.add("C"); list.add(0, "E" ); What element will be at index 2 of the list? What list will be printed after executing the method list.remove(2);
The following procedure removes the first half of the list passed as a parameter: public static void foo( List myList) { int theSize = myList.size( ) / 2; for( int i = 0; i < theSize; i++ ) myList.remove( 0 ); } What is the running time of foo if myList is a LinkedList? e(1) O e(n Ig n) O(n) O e(n³) e(n?)
Attach code in full with compilation for creating a oddIterator method that returns elements at odd indices.
Java Only Do Method, I will give LinkedList Implementation Write a method checkForEquality to be included in class KWLinkedList that does not have any parameter. Assume the list is having even number of nodes. The method returns true if the first half of the list is equal to the second half of the list in the reverse order, otherwise it returns false. If the list is empty, the method returns false; import java.util.NoSuchElementException;/** Implementation of the interface StackInt using a linked list.

Assume you have a method (shown below) inside the single linked list class, what does this method do? private E remove () { Node temp = head; if (head != nulI) { head = head.next; size--; return temp.data } else return null; } (A Remove the first node in the list and return the data of the deleted node or null if the list is empty. Remove the node after the node referenced by temp and return the data of the deleted node or null if the list is (в empty. Remove all the nodes of the linked list and return the data of the last node deleted or null if the list is empty.
When traversing a MyLinkedList moving to the next object stored in the list is done by A. using ptr=ptr.next; B. incrementing the index. C. reducing the size. D. incrementing the size. E. using head.next;
Given the doubly linked list: head tail 10 20 30 60 40 50 assuming that the Node class has three fields: prev, info, and link, what will be the list after performing the following operations?
