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

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;
}
};
// Your Solution object will be instantiated and called as such:
// Solution solution;
// solution.decode(solution.encode(url));
