std::vector :( std::vector<int> piece_list; )
                 | 1.piece_list.reserve(std::count(pieces.begin(), pieces.end(), false)); 　预留std::count个大小
                 | 2.for (std::vector<int>::reverse_iterator i = piece_list.rbegin();   i != piece_list.rend(); ++i)    　倒着走
                 | 3.find_if()---------可以参考最近的随笔
