LeetCode Brushing Questions 1491. Average wage after removing minimum wage and maximum wage

I don't know where I am going, but I am already on my way!
Time is hurried, although I have never met, but I met Yusi, it is really a great fate, thank you for your visit!

• Topic :
  give you an array of integers salary, each number in the array is unique, which salary[i]is the first iemployees of wages.
  Please return the average wages of employees after removing the minimum and maximum wages.
• Example :

示例 1 :
输入：salary = [4000,3000,1000,2000]
输出：2500.00000
解释：最低工资和最高工资分别是 1000 和 4000 。
去掉最低工资和最高工资以后的平均工资是 (2000+3000)/2= 2500

示例 2 :
输入：salary = [1000,2000,3000]
输出：2000.00000
解释：最低工资和最高工资分别是 1000 和 3000 。
去掉最低工资和最高工资以后的平均工资是 (2000)/1= 2000

示例 3 :
输入：salary = [6000,5000,4000,3000,2000,1000]
输出：3500.00000

示例 4 :
输入：salary = [8000,9000,2000,3000,6000,1000]
输出：4750.00000

• Tips :
  • 3 <= salary.length <= 100
  • 10^3 <= salary[i] <= 10^6
  • salary[i] only one.
  • And the real value of the error in 10^-5the results will be considered within the correct answer.
• Code 1:

class Solution:
    def average(self, salary: List[int]) -> float:
        salary.sort()
        return sum(salary[1:-1]) / (len(salary)-2)

• Algorithm description:
  Sort the array first, remove the maximum and minimum values, and then average.
