仅查找包含与该文件夹同名的文件的那些文件夹

我想找到所有子文件夹，其中包含具有相同名称（和扩展名.md）的markdown文件。

例如：我想查找以下子文件夹：

Apple/Banana/Orange      #Apple/Banana/Orange/Orange.md exists
Apple/Banana             #Apple/Banana/Banana.md exists
Apple/Banana/Papaya      #Apple/Banana/Papaya/Papaya.md exists

• 注意：目录中可以有其他文件或子目录。

有什么建议？

可以使用以下代码测试问题的解决方案：
