我们可以尝试使用正则表达式的环视进行替换：
查找: (?<=[a-z])\s*(?=[A-Z])
替换: ,
[<h2>Demo</h2>][1]
这里使用的正则表达式模式表示：
- `(?<=[a-z])` 断言之前是小写字母
- `\s*` 匹配可选的空白字符
- `(?=[A-Z])` 断言之后是大写字母

英文:
We can try doing a regex replacement using lookarounds:
Find: (?<=[a-z])\s*(?=[A-Z])
Replace: ,
The regex pattern used here says to match:
(?<=[a-z])assert that what precedes is a lowercase letter\s*match optional whitespace characters(?=[A-Z])assert that what follows is an uppercase letter
