Description

You are given an array of unique integers salary where salary[i] is the salary of the ith employee.

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

 

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] <= 106
• All the integers of salary are unique.

Solution(Python)

class Solution:
    def average(self, salary: List[int]) -> float:
        maxSal = 1000
        minSal = 1000000

        for s in salary:
            if s > maxSal:
                maxSal = s

        for s in salary:
            if s < minSal:
                minSal = s
        Sum = 0
        for s in salary:
            if s != minSal and s != maxSal:
                Sum += s

        return Sum / (len(salary) - 2)
