不，废话结果太多了。其中大部分都展示了如何使用for循环，while循环等
任何其他（更多）精确搜索

no, too many crap result. most of them show how to use for loop, while loop etc
any other (more) precise search

我不知道为什么这有参与递归。
首先确定究竟是什么 你在做。我认为以下是您想到的
模式：
（1）如果字符串不以Z结尾，则将其最后一个字母更改为字母表中的下一个
字母。
因此A后跟B，AA后面是AB，BLITHERA是
其次是BLITHERB等。
（2）如果字符串*确实*以Z结尾，那么，从结束开始，回到
直到你找到一个不是Z的字母，并将其改为
字母表中的下一个字母;然后用A取代之后的所有字母。
因此AZZ紧跟BAA。
（3）但如果你得到所有的开始的时候有所有的Z'，然后
用一个字母改成所有A'。
因此跟随ZZZ由AAAA。
至少我认为*这就是你的想法。是吗？如果是这样，它应该很容易用StringBuilder（这是可变的，不像String）和一些
简单的程序逻辑。
步骤（2）和（3）可以合并，因为从最后开始，你用'A'代替Z'的
。
PS当你上完作业时一定要肯定我...如果这是
作业。

I don''t see why this has to involve recursion.
First decide exactly what you''re doing. I think the following is the
pattern you have in mind:
(1) If the string does not end in Z, then change its last letter to the next
letter in the alphabet.
Thus A is followed by B, AA is followed by AB, BLITHERA is
followed by BLITHERB, etc.
(2) If the string *does* end in Z, then, starting from the end, work back
until you find a letter that is not Z, and change it to the next letter in
the alphabet; then replace all the letters after it with A.
Thus AZZ is followed by BAA.
(3) But if you get all the way to the beginning and have all Z''s, then
change it to all A''s with one more letter.
Thus ZZZ is followed by AAAA.
At least I *think* that''s what you have in mind. Is it? If so, it should
be easy to do with StringBuilder (which is mutable, unlike String) and some
simple program logic.
Steps (2) and (3) can be consolidated because, starting from the end, you''re
replacing Z''s with A''s.
P.S. Be sure to acknowledge me when you turn in your homework... if this is
homework.
