lesson 2
Consider the following recursive function.
public static int mystery(int a, int b) { if (b == 0) return0;
if (b % 2 == 0) return mystery(a+a, b/2);
return mystery(a+a, b/2) + a; }
What are the values of mystery(2, 25) and mystery(3, 11)? Givenpositive integers a and b, describe what value mystery(a, b)computes. Answer the same question, but replace + with * andreplace return 0 with return 1. Solution: 50 and 33. It computesa*b. If you replace + with *, it computes a^b.
