Ackermann's function is a recursive mathematical algorithm that can be used to test how well a computer performs recursion. Write a function A(m,n) that solves Ackermann's function. Use the following logic in your function: If m=0 then return n+1 If n=0 then return A(m-1,1) Otherwise, return A(m-1, A(m, n-1)) Test …
