Analyze the following functions:

public class Test1 {
public static void main(String[] args) {
​System.out.println(f1(3));
​System.out.println(f2(3, 0));
}
 
public static int f1(int n) {
​if (n == 0)
​return 0;
​else {
​return n + f1(n - 1);
​}
}

public static int f2(int n, int result) {
​if (n == 0)
​return result;
​else
​return f2(n - 1, n + result);
}
}

◦ f2 is tail recursion, but f1 is not
◦ f1 is tail recursion, but f2 is not
◦ f1 and f2 are both tail recursive
◦ Neither f1 nor f2 is tail recursive
