## What it is
A free open-source book (written in TeX) that serves as a modern introduction to competitive programming, covering algorithm design techniques and programming tricks. It is paired with the CSES Problem Set for practice.

## Use cases
- learn competitive programming from scratch
- study algorithm design techniques for contests
- prepare for programming olympiads like IOI or ICPC
- find practice problems to accompany an algorithms book
- review data structures and algorithms before interviews
- self-study algorithms with a free textbook

## When to choose
- you want a free, well-regarded introduction to competitive programming
- you are preparing for algorithmic contests and need technique coverage
- you want a book paired with a large problem set (CSES) for practice

## When to avoid
- you need a general software engineering or production coding guide
- you want interactive coding exercises inside the book itself
- you need a formal academic algorithms textbook with proofs

## Facets
- artifact type: learning-resource
- maturity: active
- function: documentation, developer-tools
- domain: education, programming-languages, tutorials
- platform: cross-platform
- tags: competitive-programming, algorithms, book, data-structures, tex, cses
