4. Consider the following functions defined recursively a. void Mysteryl (int N) ( if (N1) System.out print (N) else f Answer System.out print (N) Myateryl (N-1) Myateryl (N-1)1 b. void Mystery2 (int N) f if (N else f 1) System.out.print (N) Answer Mystery2 (N-1) System.out.print (N) Mystery2 (N-1) c. void Mystery3 (int N) ( if (N 1) System.out.print (N) Answer else f Mystery3 (N-1); Mystery3 (N-1); system.out.print (N) double F1 (double x, int n) if (n 0) return 0; Answer else return x + F1 (x, n-1) double F2 (int n) ( if (n
