Note that the letters array is shifted after each acronym lookup in order to search for both "ibm" and "bmx" from the string "i b m x."

注意，每执行完一次缩略词查找后都轮换字母数组中字母的位置，以便从字符串 “i b m x” 中搜索 “ibm” 和 “bmx”。

I'm doing a test there to say, x if the string x is less than the value of b, and x does not appear before b as strings, then I was going to do, oh, a couple of things, because they're at the same block level.

我正在做一个测试来看看，字符串,是不是小于b的值，而且x不在b之前作为字符串出现，如果是真的话我就要做，一系列的操作，因为他们是在同一个块等级上。
