Overview

cforces-rs is a template project for writing contests and solving problems in Rust on competitive programming contest websites.

The project mainly uses just - simpler alternative to make.

Main features include:

• Input/output in Rust - see src/template.rs.
• Common algorithms and data structures - see src/lib/.
• Creating new source files and text input/output files - see just init.
• Automatic backup of old solutions - see just save|reinit|restore.
• Testing solutions - see just run.

Supported sites

• Codeforces - cforces
• AtCoder - atcoder
• Leetcode - leetcode
• Other - recommended to use cforces configuration

Basic usage

Preparation

1. Install Rust.
2. Install just with cargo install just.
3. (Opt.) Add ~/.cargo/bin/ to your PATH.
4. Clone this repo.
5. just config <site>. See supported <site>s.

Solving problems / Competing in contests

1. just init.
2. Write your solution in main.rs.
3. (Opt) Use lib functions or data structures from src/lib/ by copying and pasting.
4. (Opt) Paste tests in input/*.in and input/*.out, test with just run.
5. Upload your solution.
6. just re <problem_id> and go back to 2.

Future work

• Expand src/lib/ - check out Rust algorithms by EbTech.
• Fully automate testing of solutions, including Leetcode
