Consider the following program:
class NN:
    def __init__(self):
        self.n = 0
    def get(self):
        self.n += 1
        return str(self.n)
    def reset(self):
        self.n = 0

class NS(NN):
    def get(self, s):
        return s + NN.get(self)

The following statements are executed in sequential order.

1) What does this print?

   foo = NS()


2) What does this print?

   print foo.get('b')

3) What does this print?

   foo.reset()
   print foo.get('c')
