Here I'll try to clear up common difficulties in understanding the problem. First of all, you need to output such b that for given a, b and t the array x is the same as given. Second, x_i is not p_i in some mapping, it is maximum of p_i of all valid mappings. Third, we consider only valid mappings, i.e. all buses should be in time.

We consider only integer sequences b. You should print "No" if there is no integer solutions.

Note that for the second sample the answer b=(3, 4) is invalid, because in this case x would be (2, 2).
