QUESTION 13 Assume that we have a highly imbalanced binary search tree, e.g., a tree with only left child nodes. What is the run time associated with searching for a value in this tree? O O(n * log n) O O(n) O o(n?) O O(log n) QUESTION 14 Suppose that we have a Java Stream that includes the following operation: .map (person -> person.getLastName () ) What does this operation do? O It creates a HashMap with the Person object as the key and the last name as the value O It maps the contents of the stream to an ArrayList called lastName O It creates a HashMap with the last name as the key and the Person object as the value O It converts the stream of Person objects to a stream of last names (presumably, Strings) QUESTION 15 Which of the these statements is true of the following HashMap declaration? HashMap< int, Student > registeredStudents = new HashMap (); O It implies that the Student class must implement the Comparable interface O The resulting HashMap of Student objects will be empty O It is invalid, because it is missing a constructor parameter O It is invalid, because an int cannot be a key
