一、
在文本处理领域，重复行的检测与去重是一个常见的需求。无论是为了数据清洗【6】，还是为了提高文本的可读性，去除重复内容都是一项重要的任务。Snobol4 语言作为一种功能强大的文本处理工具，非常适合用于此类任务。本文将详细介绍如何使用 Snobol4 语言实现文本中重复行的检测与去重。
二、Snobol4 语言简介
Snobol4 是一种高级编程语言，由David J. Farber和Ralph E. Griswold于1962年设计。它以其简洁的语法和强大的文本处理能力而闻名。Snobol4 的设计目标是简化文本处理任务，如模式匹配【7】、字符串操作【8】和文件处理。
三、Snobol4 语言特性
1. 强大的文本处理能力
2. 简洁的语法
3. 高效的执行速度【9】
4. 支持多种数据类型，包括字符串、数字和文件
四、重复行检测与去重算法设计【10】
为了实现文本中重复行的检测与去重，我们需要设计一个算法，该算法能够：
1. 读取文本文件
2. 逐行存储已读取的行
3. 检测当前行是否已存在于存储中
4. 如果存在，则跳过该行；如果不存在，则将其添加到存储中
5. 输出去重后的文本文件
五、Snobol4 代码实现
以下是一个使用 Snobol4 语言实现的重复行检测与去重程序的示例：
