Rust Algorithms
This is a collection of standard data structures and algorithmic implementations written in Rust. It provides a suite of specialized libraries designed for competitive programming and systems engineering.
The project is organized into distinct toolkits for graph theory, number theory, range queries, and string processing. It includes implementations for computing shortest paths and network flows, performing primality tests and modular arithmetic, and managing associative range queries.
The library covers broad computational areas including signal processing via fast Fourier transforms, text analysis using suffix arrays and tries, and data organization through coordinate compression and sorting utilities. It also provides tools for parsing input data from files or standard I/O.
