CF Randomizer 제작자: GodLShounak

CF Randomizer is a lightweight, fast extension designed for competitive programmers. Stop wasting time manually searching for the right practice problem on Codeforces.

How it works:
1. Enter your Codeforces handle.
2. Select your desired difficulty rating range (e.g., 1200 to 1600).
3. Enter topics/tags like "dp", "math", or "graphs".
4. Click "Get Random Problem".

The extension cross-references your previously solved problems using the public Codeforces API and opens a new tab with a randomly selected problem that you have not solved yet. It utilizes local browser storage for caching to ensure ultra-fast load times and to prevent spamming the Codeforces API.
