input: Write a python function to remove the last two digits of a number and return the remaining digits as a list of integers.
  assert remove_last_two_digits(12345) == [1, 2, 3]
  assert remove_last_two_digits(987654321) == [9, 8, 7, 6, 5, 4, 3]
  assert remove_last_two_digits(100) == [1]
output: def remove_last_two_digits(number):
      number_str = str(number)[:-2]
      return [int(digit) for digit in number_str]
