Overview

This repository contains the Rust source code for the algorithms in the textbook Algorithms, 4th Edition by Robert Sedgewick and Kevin Wayne.

The official Java source code is here.

Goals

Make a Rust implementation of the library so that a Rust programmer can follow this book easily or prefer to demonstrate the algorithms using Rust.

Try to keep the interface and variable name consistent with the original book while writing idiomatic rust code.

I hope that this project helped you understand why Rust is so wonderful and loved right now. Rust is proving to be a productive tool for reliable and efficient software. In Rust, the compiler plays a gatekeeper role by refusing to compile code with these elusive bugs, including concurrency bugs. By working alongside the compiler, you can spend your time focusing on the program’s logic rather than chasing down bugs. After you finish a day's work, go home and rest, can be at ease a good night's sleep, never worry about system crash.
