一、
前缀树是一种用于检索字符串数据集中的键的有序树数据结构。它广泛应用于字典、搜索引擎、自动补全等场景。Snobol4语言因其独特的文本处理能力，在处理字符串数据时具有天然的优势。本文将结合Snobol4语言的特点，实现前缀树数据结构，并对其实施优化。
二、前缀树基本概念
前缀树是一种树形结构，用于存储字符串数据。每个节点代表一个字符，从根节点到某个节点所经过的路径，恰好是某个字符串的前缀。前缀树具有以下特点：
1. 根节点不包含字符。
2. 从根节点到任意节点的路径，都代表一个字符串的前缀。
3. 根节点到任意节点的路径长度，等于该字符串的长度。
4. 根节点到任意节点的路径中，任意两个相邻节点代表的字符不相同。
三、Snobol4语言简介
Snobol4是一种高级编程语言，由David J. Farber等人于1962年设计。它具有以下特点：
1. 简洁的语法，易于阅读和理解。
2. 强大的文本处理能力，适用于字符串操作。
3. 支持模式匹配、递归等高级编程技巧。
四、Snobol4实现前缀树
以下是一个使用Snobol4实现前缀树的基本示例：
```
