WLW APCS EXAM QUESTIONS WITH CORRECT ANSWERS LATEST UPDATE 2025 GRADED A+ What three classes implement the List interface? - Answers Vector/LinkedList/ArrayList Is the following description a Merge Sort or Quick Sort? This sort begins by breaking the original list into to partitions (sections) based on the value of some "pivot value." once Partition will evntually contail all the elements with values greater than the pivot value. The other will eventually contain all the elements with values less than or equal to the pivot value. Repeat on each partition. - Answers Quick Sort (This is a refer to code question therefore just memorize this one) How you would write the header (signature) for the Triangle class so that it inherits the Polygon class? - Answers public class Triangle extends Polygon (This is a refer to code question therefore just memorize this one) Assume that the Triangle class inherits the Polygon class, that ply is a Polygon object, and that tri is a Triangle object. furthermore, assume that all these objects have been created and are used from within some other class that is unrelated to the Triangle and Polygon classes. Is the following legal? Vertices( ) - Answers No (This is a refer to code question therefore just memorize this one) eter( ) - Answers Yes (This is a refer to code question therefore just memorize this one) ( ) - Answers Yes (This is a refer to code question therefore just memorize this one) 1( ) - Answers Yes (This is a refer to code question therefore just memorize this one) Vertices - Answers No (This is a refer to code question therefore just memorize this one) 3( ) - Answers No What Big O value does a time complexity analysis of the following code yield? for(int j =1; j <= n; j*=2) { for(k = 0; k < n + 100; k++) { ...some code... } { - Answers O(nlog n) Show how to convert int i into a binary String. - Answers String s = IBinaryString(i); What is the value of 5! (five factorial)? - Answers None of these Static Methods are sometimes called what kind of methods? - Answers None of these Is the following a Selection Sort of an Insertion Sort? (Not gonna type out all of the code) public static void sort(int a{}) { int x, j; boolean keepGoing; for(int k = 1:k < h; k++) { itemToInsert = a[k]; ...code continues on for about half a page... - Answers Insertion What code swaps the contents of the int variables x and y? - Answers int temp = x; x = y; y = temp;
