input: Write a function to generate a random number between two given numbers. The function should take two parameters, `min` and `max`, and return a random integer between `min` and `max` (inclusive).
  
  ### Testing:
  assert random_number_generator(2, 5) in [2, 3, 4, 5]
  assert random_number_generator(1, 10) in [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
  assert random_number_generator(-5, 0) in [-5, -4, -3, -2, -1, 0]
output: import random
  
  def random_number_generator(min, max):
      return random.randint(min, max)
