Snobol4 语言 实战 基数排序算法实现与优化实战

基数排序算法实现与优化实战——以Snobol4语言为例

基数排序（Radix Sort）是一种非比较排序算法，它根据整数或字符串中数字的位数来排序。基数排序的核心思想是将待排序的元素分解成若干个位数，然后按照每个位数的值进行排序。本文将围绕Snobol4语言，实现并优化基数排序算法。

Snobol4语言简介

Snobol4是一种高级编程语言，由David J. Farber、Robert S. Beresford和John G. Kemeny于1962年设计。它是一种解释型语言，具有丰富的字符串处理功能，适合于文本处理和数据处理。

基数排序算法原理

基数排序算法的基本步骤如下：

1. 找到待排序元素中最大数的位数。
2. 从最低位开始，将所有元素分配到10个桶（桶的数量取决于待排序元素的最大位数，这里假设为10）。
3. 按照每个桶的顺序收集元素，得到新的序列。
4. 重复步骤2和3，直到最高位。

Snobol4语言实现基数排序

以下是一个使用Snobol4语言实现的基数排序算法示例：
