一、
哈希表是一种基于哈希函数【5】的数据结构，用于快速存储和检索键值对。在 Snobol4 语言中，虽然它不是一种现代编程语言，但仍然可以通过自定义函数和内置数据结构来实现哈希表。本文将介绍如何在 Snob4 中实现哈希表，并探讨其应用场景。
二、Snobol4 语言简介
Snobol4 是一种高级编程语言，由 Stephen R. Gilman 和 David J. Farber 在 1962 年设计。它主要用于文本处理，具有强大的字符串操作【6】能力。Snobol4 的语法简洁，易于理解，但它的执行效率【7】相对较低。
三、哈希表的基本原理
哈希表通过哈希函数将键映射到表中的一个位置，以实现快速查找。哈希函数将键转换为一个整数，该整数作为数组的索引。如果两个不同的键映射到同一个索引，则发生冲突【8】。解决冲突的方法有链地址法【9】、开放寻址法【10】等。
四、Snobol4 中哈希表的实现
在 Snobol4 中，我们可以使用数组来存储键值对，并定义一个哈希函数来计算键的索引。以下是一个简单的 Snobol4 哈希表实现示例：
```snobol
:hash-table
10 !size
0 !count
0 !array
:hash-function
0 !hash
0 !key
0 !i
0 !prime
'key get !key
31 !prime
0 !i
DO
!key !i mod !hash +
!hash !prime mod !hash +
!i 1 +
WHILE !i < 10
!hash
:insert
0 !key
0 !value
'key get !key
'value get !value
!hash hash-function
!index !hash !size mod
!array !index !key !value put
:lookup
0 !key
0 !value
0 !index
'key get !key
!hash hash-function
!index !hash !size mod
!array !index get !key !value put
