一、

随着互联网的快速发展，信息量呈爆炸式增长，文本数据的处理成为了一个重要课题。文本查重与去重是信息处理中的基本任务，旨在检测文本内容是否重复，并去除重复的部分。本文将介绍如何使用Snobol4语言实现这一功能。

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。它以处理文本数据而闻名，具有强大的字符串操作^【5】和模式匹配^【6】功能。Snobol4的语法简洁，易于理解，特别适合于文本处理任务。

三、文本查重与去重系统设计

1. 系统需求分析^【7】

（1）输入：系统应能接受任意长度的文本输入。

（2）输出：系统应输出查重结果^【8】，包括重复文本的行号和内容。

（3）去重：系统应能去除重复的文本行。

2. 系统设计

（1）数据结构

在Snobol4中，可以使用数组^【9】来存储文本行。数组中的每个元素代表一行文本。

（2）算法^【10】

文本查重与去重算法如下：

a. 读取输入文本，按行存储到数组中。

b. 遍历数组，对每一行文本进行去重处理。

c. 对于当前行，遍历数组中的其他行，比较当前行与其他行的内容。

d. 如果发现重复的文本行，记录下重复行的行号和内容。

e. 输出查重结果。

f. 去除重复的文本行。

3. Snobol4代码实现

以下是一个简单的Snobol4代码示例，用于实现文本查重与去重功能：
