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.
