STL - vector algorithm

// create vector with elements from 1 to 6 in arbitrary order
    vector<int> coll = { 2, 5, 4, 1, 6, 3 };

    // find and print minimum and maximum elements
    auto minpos = min_element(coll.cbegin(), coll.cend());
    cout << "min: " << *minpos << endl;
    auto maxpos = max_element(coll.cbegin(), coll.cend());
    cout << "max: " << *maxpos << endl;

    cout << "original vector:" << endl;
    ContainerUtil<vector<int>>::printElements(coll);
    // sort all elements
    sort(coll.begin(), coll.end());
    cout << "after sorting:" << endl;
    ContainerUtil<vector<int>>::printElements(coll);
    
    // find the first element with value 3
    // - no cbegin()/cend() because later we modify the elements pos3 refers to
    auto pos3 = find(coll.begin(), coll.end(), 3);                     

    // reverse the order of the found element with value 3 and all following elements
    reverse(pos3, coll.end());
    cout << "after reverse from the position of value 3:" << endl;
    ContainerUtil<vector<int>>::printElements(coll);

运行结果:

min: 1
max: 6
original vector:
  2  5  4  1  6  3
after sorting:
  1  2  3  4  5  6
after reverse from the position of value 3:
  1  2  6  5  4  3
