input: Write a python function to generate an array of 100 random integers between 1 and 100.
  assert len(generate_random_array()) == 100
  assert all(1 <= num <= 100 for num in generate_random_array())
  assert isinstance(generate_random_array(), list)
output: import random
  
  def generate_random_array():
      return [random.randint(1, 100) for _ in range(100)]
