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] <= 10⁶
• 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);
}
