A super disgusting question... An error was found for an hour .... 1. Use C ++ and G ++ to access wa. 2. Check the boundary. 3. Pay attention to the marked decentralization mode. #include #include #include #include

Notes for a single mode: 1) To design a single pattern, we first need to privatize the constructor so as not to allow external access, so the outside can only obtain a new class through the provided functions. (2) In the single mode of C ++,
