Question 1

What are the base cases in the following recursive method?

public static void xMethod(int n) {
​if (n > 0) {
​System.out.print(n % 10);
​xMethod(n / 10);
​}
}

◦ n <= 0
◦ n < 0
◦ n > 0
◦ no base cases

Question 2

Analyze the following recursive method.

public static long factorial(int n) {
​return n * factorial(n - 1);
}

◦ Invoking factorial(1) returns 1.
◦ Invoking factorial(0) returns 0.
◦ Invoking factorial(2) returns 2.
◦ Invoking factorial(3) returns 6.
◦ The method runs infinitely and causes a StackOverflowError.
