Overview

Chrome extension with Firebase

Struggling with a Codeforces problem but don’t want to jump straight to the solution? Often, easy problems feel straightforward, but when you move to more difficult problems, you suddenly get stuck even though it feels like you’re very close to the solution. In these moments, you don’t need the full editorial yet; you just need a small push in the right direction. This extension provides progressive, step-by-step hints that help you unlock the core idea behind problems while still letting you solve them on your own. It doesn’t replace Codeforces editorials, instead, it bridges the gap between simple problems and more challenging ones. Each hint is designed to: - Preserve the original mathematical notation and variables. - Follow editorial-style reasoning. - Reveal only the necessary insight at each step. To keep things engaging, the extension uses a coin-based hint system. - Each hint costs 10 coins, so you think before revealing it. - A successful submission gives 50 coins, and daily activity adds 20 more. This way, hints are used only when you’re actually stuck. You solve more problems, earn coins, and use them wisely. Why use this extension? - Move beyond easy problems: get unstuck on harder ones without spoiling the solution. - Stay in problem-solving mode: think actively instead of reading full answers. - Editorial-aligned: makes editorials easier to understand when you do read them. - Clean & non-intrusive: blends seamlessly into the Codeforces problem page, simple and direct to use.
