Everything related to algorithm contests (competitive programming).

Tested under WSL/Ubuntu with g++.

Install Ubuntu 20.04.5 LTS under WSL2, or natively - or a compatible environment.

Optional: install Homebrew for a good binary package manager (brew).

sudo apt install g++

Best to install node version 16 using nvm.

After installing node, check pnpm documentation for recommended installation methods - possibly npm i -g pnpm.

sudo apt install nlohmann-json3-dev

Use Ctrl + `.

pnpm install

This will also pre-compile bits/stdc++.h headers into .pch folder, for both debug and release configurations.

Code (hence c) the solution for task/problem a:

c a

This opens or creates task/a/a.cpp file from template.

Open another integrated terminal using Ctrl + Shift + 5.

Start the watch mode and keep it visible to see live compilation errors.

w

This is the same as w a - the CLI uses last program by default.

Run the program (go; hence g):

g

Or:

aa

There are Bash aliases for tasks a (aa), b (bb), ...

If you're using watch mode, it should automatically run your tests.

Put *.in and *.out files inside task/a/test/. Use any nested directory structure.

Manually run tests:

t

Copy the solution to clipboard (s for submit):

s

Paste into your online judge system.

Most commands allow omitting the program argument. Last program that you worked on will be used by default.

The CLI state is saved to .state.json.
