1. Consider the recursive method whose definition appears below. public static String mysteryString (String sX if (s.length ()s# 1) return s; else return s.substring (s.lenght 0-1) + mysteryString (s.substring (O, s.length 0-1)): What is the result of the following call? Why? System.out.printin (mysteryString ("computer") a. computer is printed to the screen. b. retupmoc is printed to the screen. c. c is printed to the screen d. A stack fault occurs. e. A StingindexOutOfBoundsException is thrown. Questions 2 and 3 refer to the following recursive method definition. public static int foo (int n) if(n
