Python 3! The Ackermann function, A(m, n), is defined:

Write a function named ack that evaluates the Ackermann function. Use your function to evaluate ack(3, 4), which should be 125. What happens for larger values of m and n?

n+ 1 A(m - 1,1) A(m-1, A(m, n-1)) ifm=0 fm0 and ifm>0and n > 0. A(m,n) 0
