如何在C ++中减小较小的字符串中的较大的字符串？可能是通过散列？ [英] How to reduce a bigger string in smaller string in C++? Probably by hashing?

问题描述

我想在C ++中将更大的字符串压缩成更小的字符串。在C ++中有什么不同的方法？要求是输出也应该是字符串。

I want to compress a bigger string into a smaller string in C++. What are the different ways to do this in C++? The requirement is that output should also be a string.

推荐答案

好吧，如果您以后不需要解压缩：

Well, if you don't need to uncompress it later:

string s = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
s = "";

编辑：听起来像你想要一个哈希函数 - 在那里，根据您的要求。 Google是您的朋友。

Sounds like you want a hash function - there are a zillion out there, depending on your requirements. Google is your friend.
