To much code, you can use it like this:

#include
#include

int main()
{
    std::array vec = { 1,2,3,4,5,6,7,8,9 };

    std::sort(std::begin(vec), 
              std::end(vec), 
              [](int a, int b) {return a > b; });

    for (auto item : vec)
      std::cout << item << " ";

    return 0;
}

Replace "vec" with your class and that's it.
