在看完这些之后，我想知道什么是Ruby中的循环顺序？哪个字符是最高优先级，哪个字符是最低优先级？很抱歉如果这个问题是基本的。我只是没有找到任何人都知道的网站。如果您对这个问题有疑问，可以问一下。我希望这已经足够清楚了！
解决方案
顺序是由字母的二进制表示定义的。而这又是由一个标准定义的。使用的标准是ASCII（美国信息交换标准代码）。

After seeing this, I wondered to myself "what is the loop order in Ruby?" What character is the highest priority and which is the lowest priority? Sorry if this question is basic. I just haven't found a site where anyone knows. If you have questions about the question just ask. I hope this is clear enough!
解决方案
The order is defined by the binary representation of the letters.  Which, in turn, is defined by a standard. The standard used is ASCII (American Standard Code for Information Interchange).

Other encoding standards exist, like EBCDIC which is used by IBM mid-range computers.
