- 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 Codec: ???def __init__(self): ???????self.url = {} ???????self.count = 0 ???def encode(self, longUrl): ???????"""Encodes a URL to a shortened URL. ???????:type longUrl: str ???????:rtype: str ???????""" ???????self.count += 1 ???????self.url[self.count] = longUrl ???????return ‘http://tinyurl.com/‘ + str(self.count) ???def decode(self, shortUrl): ???????"""Decodes a shortened URL to its original URL. ???????:type shortUrl: str ???????:rtype: str ???????""" ???????return self.url[int(shortUrl.split(‘/‘)[-1])] ???????# Your Codec object will be instantiated and called as such:# codec = Codec()# codec.decode(codec.encode(url))535. Encode and Decode TinyURL
