input: Write a function to find the largest three numbers in a list. If the list has fewer than three numbers, it should return the entire list sorted in ascending order. The function should return a list of the largest three numbers.
  assert find_largest_three([1, 6, 3, 8, 7, 4])==[6, 7, 8]
  assert find_largest_three([9, 2, 5])==[2, 5, 9]
  assert find_largest_three([4, 1])==[1, 4]
  assert find_largest_three([10, 20, 30, 40, 50, 60, 70])==[50, 60, 70]
  assert find_largest_three([])==[]
output: def find_largest_three(nums):
      return sorted(nums)[-3:] if len(nums) >= 3 else sorted(nums)
