Question: Consider the following recursive definition. Acker(m, n) = n + 1, if m = 0; Acker(m, n) = Acker(m - 1, 1), if n =

Consider the following recursive definition.

Acker(m, n) = n + 1, if m = 0;

Acker(m, n) = Acker(m - 1, 1), if n = 0;

Acker(m, n) = Acker(m 1, Acker(m, n 1)), otherwise.

This function, called Akermanns function, is of interest because it grows rapidly with respect to the sizes of m and n. Write a program to find Acker(1, 2). Can you find Acker(1, 2) without using computer?
