PLEASE WHAT ARE THE OUTPUTS FOR THE FOLLOWING CODES? COURSE DATA structures

8. public static long factorial (int n) { if (n = 0) // Base case return 1; else return n* factorial (n - 1); // Recursive call 9. public static void main(String...strings) { n - 12345; xMethod (n); public static void xMethod (int n) { if (n > 0) { System.out.print (n% 10); xMethod (n / 10); 10. public static long fib(long index) { if (index = 0) // Base case return 0; else if (index = 1) // Base case return 1; else // Reduction and recursive calls return fib(index - 2) + fib(index - 1); 11. when n =10, it returns? static int xMethod (int n) { if (n = 1) return 1; else return n + xMethod (n - 1)
