 - 使用列表（动态数组）代替链表，从而简化代码。在这种设定下，哈希表（数组）包含多个桶，每个桶都是一个列表。
 - 以下实现包含哈希表扩容方法。当负载因子超过 $0.75$ 时，我们将哈希表扩容至 $2$ 倍。

 值得注意的是，当链表很长时，查询效率 $O(n)$ 很差。**此时可以将链表转换为“AVL 树”或“红黑树”**，从而将查询操作的时间复杂度优化至 $O(\log n)$ 。

 - 我们使用一个固定的键值对实例 `removed` 来标记已删除元素。也就是说，当一个桶内的元素为 $\text{None}$ 或 `removed` 时，说明这个桶是空的，可用于放置键值对。
 - 在线性探测时，我们从当前索引 `index` 向后遍历；而当越过数组尾部时，需要回到头部继续遍历。

 ### 多次哈希
 
 顾名思义，多次哈希方法是使用多个哈希函数 $f_1(x)$、$f_2(x)$、$f_3(x)$、$\dots$ 进行探测。
