input: Write a function to generate a random integer between two given numbers.
  assert 1 <= generate_random_integers(1, 10) <= 10
  assert 50 <= generate_random_integers(50, 100) <= 100
  assert 200 <= generate_random_integers(200, 300) <= 300
output: import random
  
  def generate_random_integers(start, end):
      return random.randint(start, end)
