/**
 * 535. Encode and Decode 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 a class to encode a URL and decode a tiny URL.
 * 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.
 * Implement the Solution class:
 * - Solution() Initializes the object of the system.
 * - String encode(String longUrl) Returns a tiny URL for the given longUrl.
 * - String decode(String shortUrl) Returns the original long URL for the given shortUrl. It is guaranteed that the given shortUrl was encoded by the same object.
