# Overview

I use this repository as a study playground for programming contests, which contains my personal notes and implementations. Note that this is a publish-only repository, so all pull requests will be ignored.

The **folders structure** is following:

- [`notebook`](./notebook): well-explained implementation of general-purpose algorithms.
- [`scripts`](./scripts): small scripts for automatizing some repetitive tasks.
- [`solutions`](./solutions): code of accepted problems, categorized by online judges.
   - [`README.md`](./solutions/README.md): solutions index by themes, containing difficulty, name, description and hint of the problem.
