input: Write a function to generate a random number between two given numbers, inclusive of both.
  
  def random_number_generator(min, max):
      return random.randint(min, max)
  
  assert random_number_generator(2, 5) in [2, 3, 4, 5]
  assert random_number_generator(7, 11) in [7, 8, 9, 10, 11]
  assert random_number_generator(1, 3) in [1, 2, 3]
  assert random_number_generator(0, 0) == 0
  assert random_number_generator(-3, -1) in [-3, -2, -1]
output: def random_number_generator(min, max):
      return random.randint(min, max)
