This is my library of reference code for competitive programming. The goal is to write generic, fast, and clean algorithm implementations for use in contests like CodeForces or ICPC.

Build using

cmake -B build
cmake --build build

Test with

ctest --test-dir build

or directly with

./build/tests

All code in this book is written by me and CC0 licensed unless otherwise noted in the file. Inspiration is largely drawn from KACTL (https://github.com/kth-competitive-programming/kactl/) and other references.
