[1491. Average Salary Excluding the Minimum and Maximum Salary](https://leetcode.com/problems/average-salary-excluding-the-minimum-and-maximum-salary/)

### 題目描述

You are given an array of **unique** integers `salary` where `salary[i]` is the salary of the i^th^ employee.

Return *the average salary of employees excluding the minimum and maximum salary.* Answers within 10^-5^ of the actual answer will be accepted.

### 範例

**Example 1:**

Input: salary = [4000,3000,1000,2000]
Output: 2500.00000
Explanation: Minimum salary and maximum salary are 1000 and 4000 respectively.
Average salary excluding minimum and maximum salary is (2000+3000) / 2 = 2500

**Example 2:**

Input: salary = [1000,2000,3000]
Output: 2000.00000
Explanation: Minimum salary and maximum salary are 1000 and 3000 respectively.
Average salary excluding minimum and maximum salary is (2000) / 1 = 2000

**Constraints**:

* 3 <= `salary.length` <= 100
* 1000 <= `salary[i]` <= 10^6^
* All the integers of `salary` are **unique**.

### 解答

#### Javascript

function average(salary) {
  let min = Infinity;
  let max = -Infinity;
  let sum = 0;
  for(const s of salary){
    min = Math.min(min, s);
    max = Math.max(max, s);
    sum += s;
  }

  return (sum - min - max) / (salary.length - 2);
}

#### Python

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