input: Write a function to generate a random number between two given numbers as input. If the inputted minimum value is greater than the maximum value, return "Invalid Range".
  assert random_number_generator(2, 5)!="Invalid Range"
  assert random_number_generator(5, 2)=="Invalid Range"
  assert random_number_generator(-10, 10)!="Invalid Range"
output: import random
  
  def random_number_generator(min_val, max_val):
      if min_val > max_val:
          return "Invalid Range"
      return random.randint(min_val, max_val)
