Answer:
Explanation:
public class Ackermann {
public static int ackermann's(int m, int n) {
if (m == 0) {
return n + 1;
} else if (n == 0) {
return ackermann's(m-1, 1);
} else {
return ackermann(m - 1, ackermann(m, n - 1));
}
}
public static void main(String[] args) {
System.out.println(ackermann(0, 0));
System.out.println(ackermann(0, 1));
System.out.println(ackermann(1, 1));
System.out.println(ackermann(1, 2));
System.out.println(ackermann(1, 3));
System.out.println(ackermann(2, 2));
System.out.println(ackermann(3, 2));
}
