描述
Given an array of unique integers salary where salary[i] is the salary of the employee i.
Return the average salary of employees excluding the minimum and maximum salary.
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
Example 3:
Input: salary = [6000,5000,4000,3000,2000,1000]
Output: 3500.00000
Example 4:
Input: salary = [8000,9000,2000,3000,6000,1000]
Output: 4750.00000
Note:
- 3 <= salary.length <= 100
- 10^3 <= salary[i] <= 10^6
- salary[i] is unique.
- Answers within 10^-5 of the actual value will be accepted as correct.
解析
根据题意，只需要去除列表中最大和最小的数字，用剩下的数字求平均数即可。
解答
class Solution:
def average(self, salary: List[int]) -> float:
return (sum(salary)-min(salary)-max(salary))/(float)(len(salary)-2)
