重复遍历数组，比较相邻元素，如果顺序错误就交换
Guar gum, a plant colloid, costs less than agar and is better suited for growing thermophilic bacteria, but is also more difficult to handle, being more viscous and less transparent. The bacterial polysaccharide xanthan is cheaper as well but forms weaker jellies that, as with carrageenan, might result in puncturing its surface. Other colloids, like alginate (from brown seaweed) and gellan gum (from a bacterium), don’t set solely based on temperature and require additives for gelation. These additives might interfere with microbial growth and make the preparation of those jellies less handy than agar plates.

当前，“新质生产力”成为发展热词。习近平总书记叮嘱：“新质生产力，是否就等于新兴产业？传统产业改造升级，也能发展新质生产力。不能光盯着‘新三样’，不能大呼隆、一哄而起、一哄而散，一定要因地制宜，各有千秋。”这番重要论述，说的也是“适配度”。
