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
Constraints:
3 <= salary.length <= 10010^3 <= salary[i] <= 10^6salary[i] is unique.10^-5 of the actual value will be accepted as
correct.
