4. Consider the following C++ statements (The class unorderedLinked List is as defined in this chapter). What is the output of this program segment?

unorderedLinkedList list;

list.insertFirst(26);

list.insertFirst(36);

list.insertLast(15);

list.insertFirst(72);

list.insertLast(48);

list.insertLast(45);

list.insertFirst(88);

list.deleteNode(66);

list.insertFirst(82);

list.deleteNode(15);

list.deleteNode(82);

linkedListIterator it;

for (it = list.begin(); it != list.end(); ++it)

cout << *it << " ";

cout << endl;
