in the logical layer of the algorithm written into the two parts (so there is the MVC, MVP and other modes to avoid this situation). Second, the two parts communicate with the logical layer in the form of messages or events, and once the same data needs to be displayed/modified in more ways, the code used for synchronization is complicated; Finally, D and e are mutually inverse pairs. But it needs to be separate to write-----display data write an algorithm, modify the data and then write an alg
