Assume that the following method is added to the class KWLinkedList. What does this method do? public boolean question() { if (size%2 == 1 || size < 2) return false; Node<E> h = head; for(int i = 0; i < size/2; i++) h=h.next; Node<E> p = head; while (h!= null) { if (! p.data.equals(h.data)) return false; p = p.next; h = h.next; } return true; } Compare the elements of the first half of the list with the second half, if any one node has the same data value, it will return false, else it will return true. Compare the elements of the first half of the list with the second half, if all the nodes have the same data values, it will return true else, it will return false.

Write a method called InsertAfter to be included in the KWLinkedList class, the method has three parameters p1, p2 and p3 of type E. The list has at least two nodes (no need to check). The method inserts a node having its data as p3 after a node having data as p2 if preceded with a node having data as p1 (after insertion it will be .p1.p2.p3.), then quits. You must use iterator to solve the problem. The method head is public void insertAfter(E p1, E p2, E p3) Example: Before run: Assume p1:5 p2: 7 p3: 100 List: 2 58 57 12 10 576 After run: List: 2 5 8 5 7 100 12 10 5 7 6

Design and implement a getLastHalf() method for the MyLinkedList class. The method should return the last half of the list as a new list leaving the original list intact. If the list has an uneven number of elements the extra one element must be in the list returned. Example : [1,3,5,4] return [5,4] and [1,6,9] return [6,9]. Follow the three step method for designing the method Develop the java code for the method Create a test program to test the method thoroughly using the Integer wrapper class.

Add a new method in UnweightedGraph with the followingheader to return two bipartite sets if the graph is bipartite:public List<List<Integer>> getBipartite();The method returns a List that contains two sublists, each of which contains aset of vertices. If the graph is not bipartite, the method returns null.
What should the return type be in each of the following methods? getData() --> getLeft() --> getRight() --> 2. What should the parameter type be in each of the following methods? setData() --> setLeft() --> setRight() --> 3. What would need to be added/removed/changed to make this class work for a more general tree such that each node could have more than 2 nodes? EXERCISE 2 4. What is the base case of the size() method? What are the recursive cases? 5. What is the main difference between the 3 methods: inorder(), preorder(), and postorder()? 6. In the recFormatTree() method, what is the space parameter used for? What is the default value when this method is first called? What is being concatenated to this space value in the recursive calls? Does this make sense for how the tree is being displayed?

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, ObjectnewElement){//to do} insertBefore (head, 3, 50).
java program : Given the following method to be considered within the SingleLinkedList class, what does this method do? public void Undefined() { Node<E> ptr = head; if (ptr == null || ptr.next == null) return false; E item1 = ptr.data; while (ptr.next != null) ptr = ptr.next; E item2 = ptr.data; if (item1.equals(item2)) { head = head.next; size--; } } If the first element of the list is equal to the second element of the list, then the method deletes the second node. If the first element of the list is equal to the last element of the list, then the method deletes the first node. If the first element of the list is equal to the second element of the list, then the method deletes the first node. If the first element of the list is equal to the last element of the list, then the method deletes the last node.
I am learning about Depth First Search Graphs in class. In the book we use for class, this pseudocode came up that explains a basic depth-first-search algorithm. I am trying to implement the pseudocode into actual code and I honestly just don't know where to start. I am trying to write an adjacency list, so would that mean that I would have a LinkedList to store an array in? Or is an ArrayList a better choice?
