3、代码

 vector<vector<int>> flipAndInvertImage(vector<vector<int>>& A) {
         for( vector<vector<int>>::iterator it = A.begin() ; it != A.end() ; it++ )
         {
             for(auto it_b = (*it).begin() ,it_e = (*it).end()- ; it_b <= it_e ; it_b++ ,it_e-- )
             {
                 int tmp = *it_b;
                 *it_b = *it_e;
                 *it_e = tmp;

                 if( it_b != it_e )
                 {
                    *it_b = ( *it_b == ) ?  : ;
                    *it_e = ( *it_e == ) ?  : ;
                 }else{
                     *it_b = ( *it_b == ) ? : ;
                 }
             }
         }
         return A;
