[C++] max_element 와 find로 해당 값 인덱스 찾기

int max_num = *std::max_element(vec.begin(), vec.end());
int min_num = *std::min_element(vec.begin(), vec.end());

auto max_num_index =
    (std::find(vec.begin(), vec.end(), max_num) - vec.begin());
auto min_num_index =
    (std::find(vec.begin(), vec.end(), min_num) - vec.begin());
