Quiz 3 CS 2110 March 15 Name: NetId: 1. Suppose we are making a method that prints Lists with elements of any type. What would be an appropriate signature for this method? (a) public void print(List<Object> list) (b) public void print(List < ? > list) (c) public void print(LinkedList<? extends Comparable> list) (d) public void print(List<? extends Comparable> list) 2. Select the statement that is false. (a) Binary search in a sorted array with n elements has average-case time complexity O(log(n)) . (b) Binary search in a sorted array with n elements has worst-case time complexity O(log(n)) . (c) Finding an element in a BST with

Unformatted text preview: n elements has worst-case time complex-ity O ( log ( n )) . (d) Inserting n elements into an unsorted linked list can be done in worst-case time O(n) . 3. What is the time complexity of the code below? Choose the tightest bound. int count = 0; for(int i = 0; i < n + 5; i++){ for(int j = 0; j < n*n*n; j++){ count++; } } (a) O( n 4 ) (b) O( n 3 ) (c) O( n 2 ) (d) O( n ) 4. Which of these is a design pattern? (a) Scientist (b) Observer (We gave everyone this point as it wasn’t covered in class before the quiz) (c) Sniper (d) Engineer 1...
