这篇博客主要介绍了如何在IDEA中修改SpringBoot项目配置文件application.properties的默认编码，确保其以UTF-8格式保存。通过File > Settings > File Encodings设置Properties Files的Default encoding for properties files为UTF-8，并启用Transparent native-to-ascii conversion，可以避免编码导致的乱码问题。

直接点说就是SpringBoot的application.properties默认不是以UTF-8格式编码的，所以需要你修改下
那么就直接在IDEA中
File -> Settings -> File Encodings
在这里插入图片描述
将Properties Files下的 Default encoding for properties files修改为UTF-8
并且勾选上Transparent native-to-ascii conversion

WhiteGrass99: We want to find conditions under which the graph is a bipartite graph, meaning it contains no odd cycles. Therefore, the case of one odd and one even doesn't hold. We aim for both to be odd. To minimize the number of deletions, we express all numbers in B as 2^k * v, where v is an odd number. Only when the exponents k are equal for two numbers, b/gcd(a,b) and a/gcd(a,b) will both be odd. Hence, the retained elements are those with the highest exponents, ranging from 2^0 to 2^63.

WhiteGrass99: roperty of Bipartite Graph: A graph is bipartite if and only if it does not contain an odd cycle. Utilizing this property, we first consider connecting integers that meet the condition, i.e., when the absolute difference between two integers is in B. For two points a and b existing in B, they can be seen as starting from 0 and advancing forward by a and b steps respectively each time. Therefore, their first meeting point occurs at the least common multiple (LCM) of a and b. At this meeting point, after a has moved b/gcd(a,b) times and b has moved a/gcd(a,b) times, to ensure the absence of an odd cycle, we need the sum of these steps to be divisible by 2. Hence, the problem can be reduced to two cases: Both b/gcd(a,b) and a/gcd(a,b) are odd. One is odd and the other is even. It's impossible for both to be even since if they were both even, it means their denominators can be further divided by 2, contradicting the property of gcd.
