C ベクトル内の最大値または最小値を効率的に見つけるにはどうすればよいでしょうか?

<code class="cpp">#include <vector>
#include <algorithm>

int main() {
  std::vector<int> vector = {1, 2, 3, 4, 5};

  // Getting the maximum value
  int max = *std::max_element(vector.begin(), vector.end());
  std::cout << "Maximum: " << max << std::endl;

  // Getting the minimum value
  int min = *std::min_element(vector.begin(), vector.end());
  std::cout << "Minimum: " << min << std::endl;

  // Using iterators
  std::vector<int>::iterator it_max = std::max_element(vector.begin(), vector.end());
  std::cout << "Element with maximum value: " << *it_max << std::endl;
}

<code class="cpp">int main() {
  int array[5] = {1, 2, 3, 4, 5};

  // Getting the maximum value
  int max = array[0];
  for (int i = 1; i < 5; i++) {
    if (array[i] > max) {
      max = array[i];
    }
  }
  std::cout << "Maximum: " << max << std::endl;
}</code>
