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.
