Shortener Url Code Challenge

Solution

Let us assume the short URL looks like this: http://shortener.com/{hashValue}. To support the URL shortening use case, we must find a hash function encode that maps a long URL to the hashValue.

The hash value is made up of characters of [0-9, a-z, A-Z], containing 10 + 26 + 26 = 62 possible characters. If we are going to support at most 8 characters as a hash value, the service able to support up to 3.5 trillion URLs(n = 7, 62 ^ n = ~3.5 trillion)

Domain
