s Analyze the following two programs: A: public class Test [ public static void main/(Stringl) args)( xMethod(5) public static void xMethod(int length) if (length > 1) System.out.print(length-1)+" xMethod(length-1): B: public class Test public static void main(Stringl) args) xMethod(S) public static void xMethod(int length) f while (length > 1) System.out.print(length-1)+"" xMethod(length-1); a. The two programs produce the same output 5 4 321. b. The programs produce the same output 1 2 345 c. The two programs produce the same output 43 21. d. The two programs produce the same output 1234 e. Program A produces the output 4 3 2 1 and Program B prints 4 3211 1 infinitely. Anal lyze the following functions; public class Test1 ( public static void main(Stringll args) System.out.println(f1(3)); System.out.printin(f2(3, 0)); public static int f1(int n) if (n0) return 0; else return n + fi(n- 1); public static int f2(int n, int result)f if (n0) return result; else return f2(n - 1, n+result); a. fl is tail recursion, but f2 is not b. f2 is tail recursion, but f1 is not c. f1 and f2 are both tail recursive d. Neither f1 nor f2 is tail recursive
