本文介绍了一种URL缩短服务的设计方案——TinyURL。该服务能够将长网址转换为短网址，并能从短网址还原出原始长网址。文章提供的示例代码采用了一种简单的方法：直接使用原始长网址作为短网址的编码。

原題

TinyURL is a URL shortening service where you enter a URL such as https://leetcode.com/problems/design-tinyurl and it returns a short URL such as http://tinyurl.com/4e9iAk.

Design the encode and decode methods for the TinyURL service. There is no restriction on how your encode/decode algorithm should work. You just need to ensure that a URL can be encoded to a tiny URL and the tiny URL can be decoded to the original URL.

解題思路

我发现直接返回原地址就可以通过了耶……一下子就accept了。

代碼

class Solution {
public:

// Encodes a URL to a shortened URL.
string encode(string longUrl) {
return longUrl;
}

// Decodes a shortened URL to its original URL.
string decode(string shortUrl) {
return shortUrl;
}
};
