There are n parking spots 1, 2, ..., n on a one-way street. Cars 1, 2, ..., n arrive in this order.
Each car i has a favorite parking spot f(i). When a car arrives, it first goes to its favorite spot. If
the spot is free, the car will take it, if not, it goes to the next spot. Again, if that spot is free, the
car will take it, if not, the car goes to the next spot. If a car had to leave even the last spot and
did not find the space, then its parking attempt has been unsuccessful. If, at the end of this
procedure, all cars have a parking spot, we say that f is a parking function on [n]. Prove that the
number of parking functions on [n] is (n + 1)^n-1
