input: Write a function to classify a list of numbers based on their average value.
  assert classify_numbers([1, 2, 3, 4, 5, 6, 7, 8, 9, 10]) == 1
  assert classify_numbers([1, 2, 3, 4, 1]) == 0
  assert classify_numbers([10, 20, 30, 40, 50]) == 1
  assert classify_numbers([]) == 0
output: def classify_numbers(numbers):
      if not numbers:
          return 0
      average = sum(numbers) / len(numbers)
      return 1 if average > 5 else 0
