Question

Prove by induction consider an inductive definition of a version of Ackermann’s function.

A(m, n)=

2n, if m = 0

0, if m ≥ 1, n = 0

2, if m ≥ 1, n = 1

A(m − 1, A(m, n − 1)), if m ≥ 1, n ≥ 2

 

1. Find A(1, 1).

2. Find A(1, 3).

3. Show that A(1, n) = 2n whenever n ≥ 1.

4. Find A(3, 4).
