input: Write a python function to find the top 3 highest scores from a list.
  assert find_top_scores([20, 24, 27, 30, 18, 28, 15, 25, 30, 22, 28]) == [30, 30, 28]
  assert find_top_scores([10, 20, 30, 40, 50]) == [50, 40, 30]
  assert find_top_scores([15, 25, 35, 45, 55, 65]) == [65, 55, 45]
output: def find_top_scores(scores):
      return sorted(scores, reverse=True)[:3]
