input: Write a python function to classify inputs into 'negative', 'non-negative', and 'positive' categories.
  assert classify_inputs([-2, 10, 11, 4, -1]) == ['negative', 'non-negative', 'positive', 'non-negative', 'negative']
  assert classify_inputs([0, 5, 15, -5]) == ['negative', 'non-negative', 'positive', 'negative']
  assert classify_inputs([1, 2, 3, 11, -10, 0]) == ['non-negative', 'non-negative', 'non-negative', 'positive', 'negative', 'negative']
output: def classify_inputs(numbers):
      result = []
      for num in numbers:
          if num < 0:
              result.append('negative')
          elif 0 <= num <= 10:
              result.append('non-negative')
          else:
              result.append('positive')
      return result
