input: Write a function to find the largest three numbers in a list. If the list contains fewer than three numbers, return all the numbers in the list. The function should return the numbers in a sorted order with the largest first.
  assert find_largest_three([1, 6, 3, 8, 7, 4])==[8, 7, 6]
  assert find_largest_three([10, 20, 30, 40])==[40, 30, 20]
  assert find_largest_three([5, 2, 9, 1])==[9, 5, 2]
  assert find_largest_three([2, 1])==[2, 1]
  assert find_largest_three([])==[]
output: def find_largest_three(nums):
      return sorted(nums, reverse=True)[:3]
