7a. Consider a universal URM program Pu, that is simulating another program P on some input x, where P has Godel number e. Why must Pu encode and decode the configurations associated with the computation of P on input x? For example, why does Pu have to work with toe, x, i)) rather than ole, , i)? Explain. Note: here we define ole, ,i) as the i th configuration of the computation of Pe on input x. (4 points) 7a.
