< p > 「哈希表 hash table」， ， < code > key< / code > 与值 < code > value< / code > 之间的映射，实现高效的元素查询。具体而言，我们向哈希表输入一个键 < code > key< / code > ，则可以在 < span class = "arithmatex" > \(O(1)\)< / span > 时间内获取对应的值 < code > value< / code > 。< / p >

2023-08-20 23:28:04 +08:00
< p > 我们先考虑最简单的情况，< strong > 仅用一个数组来实现哈希表< / strong > 。在哈希表中，我们将数组中的每个空位称为「桶 bucket」， ， < code > key< / code > 对应的桶，并在桶中获取 < code > value< / code > 。< / p >
< p > 那么，如何基于 < code > key< / code > 来定位对应的桶呢？这是通过「哈希函数 hash function」实现的。哈希函数的作用是将一个较大的输入空间映射到一个较小的输出空间。在哈希表中， < code > key< / code > ，输出空间是所有桶（数组索引）。换句话说，输入一个 < code > key< / code > ， < strong > 我们可以通过哈希函数得到该 < code > key< / code > 对应的键值对在数组中的存储位置< / strong > 。< / p >

< li > 通过某种哈希算法 < code > hash()< / code > 计算得到哈希值。< / li >
< li > 将哈希值对桶数量（数组长度）< code > capacity< / code > 取模，从而获取该 < code > key< / code > 对应的数组索引 < code > index< / code > 。< / li >

< p > 随后，我们就可以利用 < code > index< / code > 在哈希表中访问对应的桶，从而获取 < code > value< / code > 。< / p >
< p > 设数组长度 < code > capacity = 100< / code > 、哈希算法 < code > hash(key) = key< / code > ，易得哈希函数为 < code > key % 100< / code > 。下图以 < code > key< / code > 学号和 < code > value< / code > 姓名为例，展示了哈希函数的工作原理。< / p >

< p > 本质上看，哈希函数的作用是将所有 < code > key< / code > 构成的输入空间映射到数组所有索引构成的输出空间，而输入空间往往远大于输出空间。因此，< strong > 理论上一定存在“多个输入对应相同输出”的情况< / strong > 。< / p >
2023-06-16 21:22:53 +08:00
< p > 对于上述示例中的哈希函数，当输入的 < code > key< / code > 后两位相同时，哈希函数的输出结果也相同。例如，查询学号为 12836 和 20336 的两个学生时，我们得到：< / p >

< p > 容易想到，哈希表容量 < span class = "arithmatex" > \(n\)< / span > 越大，多个 < code > key< / code > 被分配到同一个桶中的概率就越低，冲突就越少。因此，< strong > 我们可以通过扩容哈希表来减少哈希冲突< / strong > 。< / p >
< p > 如下图所示，扩容前键值对 < code > (136, A)< / code > 和 < code > (236, D)< / code > 发生冲突，扩容后冲突消失。< / p >

< p > 类似于数组扩容，哈希表扩容需将所有键值对从原哈希表迁移至新哈希表，非常耗时。并且由于哈希表容量 < code > capacity< / code > 改变，我们需要通过哈希函数来重新计算所有键值对的存储位置，这进一步提高了扩容过程的计算开销。为此，编程语言通常会预留足够大的哈希表容量，防止频繁扩容。< / p >
2023-08-20 23:28:04 +08:00
< p > 「负载因子 load factor」是哈希表的一个重要概念， ， ， < strong > 也常被作为哈希表扩容的触发条件< / strong > 。例如在 Java 中，当负载因子超过 < span class = "arithmatex" > \(0.75\)< / span > 时，系统会将哈希表容量扩展为原先的 < span class = "arithmatex" > \(2\)< / span > 倍。< / p >
