Use the standard linked list below to answer True/False statements 9-12: 8 7 null 4 10 The “head” pointer of this list is pointing to Node 4 If we called “insert(5)”, the new node’s “next” pointer will point to Node 8 If we called “delete(10)”, Node 7’s “next” pointer will point to Node 8 If we called “search(20)”, the “head” pointer will be at Node 4 after the search function endsQuestion 11 If N represents the number of elements in the collection, then the contains method of the ArrayCollection class is O(1).

If you like, you can provide a description of your answer for partial credit in case you are incorrect. 7) Appending a new node to the end of the list is O(log n) 8) If the data is sorted in a Linked List, you can use binary search to find an element and its performance is O(log n)I need to write changeArrayLength(int m) – void method; I already have the code (attached below) but it needs debugging... This method creates a new student table for this course; this new table has the given length m; the method moves all registered students to this table. This method creates a new array of SLinkedList<Student>, moves all the registered students into these linked lists, and changes this course’s studentTable field so it references this new table instead. Each student in the current table will be moved to the new table. This will require in most cases that the student is moved to a different array slot index. The slot index for the SLinkedList<Student> that they are moved to is id % m, where m is the new length of the array (the parameter of the method). The motivation for increasing the capacity of the array is that it keeps the average lengths of the linkedlists below 1, which tends to mean a fast traversal of each linked list. public class Course {…
