Note: This is a companion problem to the System Design problem: Design TinyURL.
\n\n

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 a class to encode a URL and decode a tiny URL.

\n\n

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.

\n\n

Implement the Solution class:

\n\n\n\n

 

\n

Example 1:

\n\n
\nInput: url = "https://leetcode.com/problems/design-tinyurl"\nOutput: "https://leetcode.com/problems/design-tinyurl"\n\nExplanation:\nSolution obj = new Solution();\nstring tiny = obj.encode(url); // returns the encoded tiny url.\nstring ans = obj.decode(tiny); // returns the original url after deconding it.\n
\n\n
