推荐答案

好吧，我们不会给您代码".但是，我们可以给您一些提示.例如，您可以查看 Wikipedia B树页面 [ 请注意，您编写的代码无法编译(您知道构造函数与其他方法一样，在其主体之前需要花括号).

Well, we won''t give you ''the code''. However we can give you some hints. For instance you may have a look ath the Wikipedia B-Tree page[^] where the insertion algorithm is explained (there''s even a ''pictorial'' description).
Please note, the code you wrote doesn''t compile (you know the constructor, like other methods, needs a couple of braces, before its body).
