You’ll see pictures of long chains of linked nodes before and after changes. (The . . . in the middle of the chain signifies an indeterminate large number of nodes.) Write the code that will produce the given result by modifying links between the nodes shown and/or creating new nodes as needed. You will need to write loops to advance to the end of the list in order to reach the node(s) to modify.
