Snobol4 语言 实战 时间格式统一实战

Snobol4 语言实战：时间格式统一实战

时间格式统一是数据处理和交换中常见的问题，特别是在不同系统和平台之间交换数据时。Snobol4，作为一种古老的编程语言，虽然现代编程中不常使用，但它独特的文本处理能力使其在处理字符串和文本格式问题时仍然有其价值。本文将围绕Snobol4语言，探讨如何实现时间格式的统一。

Snobol4 简介

Snobol4（StriNg-Oriented and symBOlic Language）是一种高级编程语言，由David J. Farber等人于1962年设计。它以强大的字符串处理能力著称，特别适合于文本处理任务。Snobol4的语法简洁，易于理解，但同时也因其独特的特性而显得有些复杂。

时间格式统一问题

在现实世界中，时间格式多种多样，如“YYYY-MM-DD”、“DD/MM/YYYY”、“MM-DD-YYYY”等。为了统一这些格式，我们需要编写程序将输入的时间字符串转换为统一的格式。

实战：Snobol4 时间格式统一

以下是一个使用Snobol4语言实现时间格式统一的示例代码。我们将以“YYYY-MM-DD”格式为目标格式，将其他格式的时间字符串转换为这种格式。

```snobol
:input
input: date-string
output: unified-date
