2. The StringListNode class describes a single node in a linked list where the elements are Strings. Consider the following code. StringListNode newFirst = first; while (first . next != null) { StringlistNode temp first.next; first.next - temp.next; temp.next = newFirst; newFirst = temp; Suppose that the above mystery method is run, given that first is as below. It references a (non- encapsulated) linked list of elements "a", "b", "c" data next irst t) Figure 1 Show how this boxes and arrows diagram changes during each step of the code's execution Specifically, show the structure of the StringListNode object immediately after each execution of the statement newFirst - temp. Make sure you show exactly where temp, first, and newFirst are pointing
