Consider the recursive method whose definition appears below public static String mysteryString (String s)l if (s.length (0--1) return s; else return s.substring (s.lenght ()-1) + mysteryString (s.substring (0, s.length ()-1) What is the result of the following call? Why? System.out.println (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.
