Question 1: Node Trace A

Write the contents of the chain of nodes headed by firstNode and the value of the data in the node current. Do this for each numbered line in the code below. Use the simple method of writing a chain, such as 1->2->3.

Node n0 = new Node(88); Node n1 = new Node(12, n0); Node n2 = new Node(43, n1); Node n3 = new Node(67, n2); Node n4 = new Node(95, n3); Node firstNode = n4; // line 1 Node current = firstNode; // line 2 current = current.next; // line 3 firstNode = firstNode.next; // line 4 current.next.data = 36; // line 5 current.next = current.next.next.next; // line 6 firstNode.data = 17; // line 7 current = current.next; // line 8 firstNode.next = current.next; // line 9
