There are 24 floors in a high-end office building. The elevator starts from the first floor, and there are 5 people on it. After that, 2 people go up to each floor in the middle, and the passengers in the elevator get off the elevator after sitting on the 4th floor at most. So how many passengers will get off the elevator on the top floor at most? (regardless of overloading)
