The general code is like this, and I feel that the code using the intermediary mode is similar, so I won't introduce it much here. The code in the book has advantages, but I don't feel that there is much difference, so I no longer use the intermediary mode to write code here. State mode is an unusually excellent mode, which may be the best way to solve some requirement scenarios. Although the state mode is not a simple to clear mode (it often brings about an increase in the amount of code), once you understand the essence of the state mode, you will certainly thank it for its incomparable benefits in the future. The key to the state mode is to distinguish the internal state of things. Changes in the internal state of things often bring about changes in the behavior of things. This article describes the state mode in detailPolylactic acid (PLA) is a new bio-based and renewable biodegradable material, which is made of starch raw materials proposed by renewable plant resources (such as corn). Starch raw materials are saccharified to obtain glucose, then glucose and certain strains are fermented to produce high purity lactic acid, and polylactic acid with certain molecular weight is synthesized by chemical synthesis method. It has good biodegradability, can be completely degraded by microorganisms in nature under specific conditions after use, and finally generates carbon dioxide and water without polluting the environment, which is very beneficial to environmental protection and is recognized as an environment-friendly material. This thing is actually a long piece, and then "curled up" in it and wrapped in a cylinder shape. What's the use?
