Codeforces Problem Suggester

Recommends unsolved Codeforces problems in your target rating range directly on profile pages.

Streamline your competitive programming practice with intelligent, real-time problem recommendations directly on Codeforces profile pages. Codeforces Problem Suggester eliminates decision fatigue by evaluating a user's current rating and automatically recommending an unsolved problem within their optimal growth zone. Designed with a clean interface that matches the native Codeforces styling, it integrates seamlessly into your daily training routine. KEY FEATURES • Dynamic Rating Targeting: Automatically calculates target difficulty based on user rating (e.g., +0 to +200 rating range), clamped safely within the official 800–3500 bounds. • 3 Practice Modes: - Warm-up: Practice baseline techniques (Rating: x - 200 to x). - Standard: Target optimal growth zone (Rating: x to x + 200). - Hard: Push boundaries with advanced problems (Rating: x + 200 to x + 400). • Topic-Specific Filtering: Filter recommendations across popular topics including Dynamic Programming (DP), Greedy, Graphs, Math, Data Structures, Trees, and more. • Solved Problem Exclusion: Scans the user's submission history via official APIs to prevent recommending already-solved questions. • Spoiler Protection: Problem tags are concealed by default with an on-demand reveal toggle, ensuring an authentic contest-like solving experience. • 24-Hour Smart Caching: Caches the Codeforces problem repository locally with automatic 24-hour background invalidation, delivering instant load times and zero network overhead. • Native Interface Integration: Styled to match the Codeforces design language, including support for dynamic layouts and third-party extensions. PRIVACY & COMPLIANCE • No tracking or analytics. • No personal data collection or transmission to external third-party servers. • Communicates exclusively with official Codeforces API endpoints
