The answer is that the arguments to reverse are iterators, which are a generalization of Pointers.

答案是这个逆序函数的参数是迭代器，概括的指针。

Reverse bidirectional iterators can be used anywhere that a reverse input or reverse output iterator is required.

无论是需要反向输入迭代器还是反向输出迭代器，均可以使用反向双向迭代器。

youdao

Constant reverse bidirectional iterators can be used anywhere that a constant reverse input or constant reverse output iterator is required.

无论是需要常量反向输入迭代器还是常量反向输出迭代器，均可以使用常量反向双向迭代器。
