LeetCode 1491. Average Salary Excluding the Minimum and Maximum Salary

class Solution {
public:
    double average(vector<int>& salary) {
        int size = salary.size();
        double sum = 0;

        pair<int, int> max = {*max_element(salary.begin(), salary.end()), max_element(salary.begin(), salary.end()) - salary.begin()};
        pair<int, int> min = {*min_element(salary.begin(), salary.end()), min_element(salary.begin(), salary.end()) - salary.begin()};

        for(int i = 0; i<size; i++)
        sum += (double)salary[i];
        sum = max.second == min.second ? (sum-max.first)/((double)size-1.0) : (sum-max.first-min.first)/((double)size - 2.0);
        return sum;
    }
};
