input: Write a python function to classify an object based on its features and classes.
  assert classify_object([2.5, 4.5, 2.5], ["apple", "orange", "pear"]) == "orange"
  assert classify_object([1.1, 3.3, 2.2], ["cat", "dog", "mouse"]) == "dog"
  assert classify_object([7, 1, 5], ["car", "bike", "boat"]) == "car"
output: def classify_object(features, classes):
      max_index = features.index(max(features))
      return classes[max_index]
