Encode and Decode TinyURL

MediumArrays
Open on LeetCode

Design encode(longUrl) that returns a short URL and decode(shortUrl) that recovers the original. Any consistent reversible scheme works.

Input format (stdin): the first line has q. Each next line is a long URL to encode then immediately decode. For each, print the decoded URL, which must equal the original.

Examples
Input: 2 https://example.com/a https://example.com/b
Output: https://example.com/a https://example.com/b
Each URL round-trips through encode/decode unchanged.
Constraints
  • 1 <= q <= 10^4
  • URLs are valid strings
