Question1 1 pts Suppose our new improved queue contains n elements that have been added to it. What is the best characterization of the big-O runtime to add one additional member to this queue? Assume that constructing a new StringNode object is an O(1) (constant time) operation Here's the relevant code for the queue and node: public class ImprovedQueue public StringNode head; public StringNode tail; public ImprovedQueueO head tail null; // empty queue public void add(String x) i /Add x to the end of the list if Cheadnull) 1// Nobody in line head = tail new StringNodex, null); // head and tail are the o ne person in line } else I/ Tail must not be null tail.next -new StringNode(x, null); /7 Put the new tail after th e old tail tail - tail.next; public class StringNode f public String data; public StringNode next; // null at the end public StringNode(int data, StringNode next) { this.data-data; this.next - next; O(n) O(n3)
