Analyze the following two programs:

```
A:

public class Test {
public static void main(String[] 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(String[] args) {
xMethod(5);
}

public static void xMethod(int length) {
while (length > 1) {
System.out.print((length - 1) + " ");
xMethod(length - 1);
}
}
}```
a. The two programs produce the same output 5 4 3 2 1.
b. The two programs produce the same output 1 2 3 4 5.
c. The two programs produce the same output 4 3 2 1.
d. The two programs produce the same output 1 2 3 4.
e. Program A produces the output 4 3 2 1 and Program B prints 4 3 2 1 1 1 .... 1 infinitely.

e In Program B, xmethod(5) invokes xmethod(4), xmethod(4) invokes xmethod(3), xmethod(3) invokes xmethod(2), xmethod(2) invokes xmethod(1), xmethod(1) returns control to xmethod(2), xmethod(2) invokes xmethod(1) because of the while loop. This continues infinitely.
