LC 535. Encode and Decode TinyURL
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.
Runtime: 4 ms, faster than 99.57% of C++ online submissions for Encode and Decode TinyURL.
funny.
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));
