Running

If you use nix you can run nix develop (or use direnv) to get a shell with all the required dependencies. Then cd to the specific language folder and run the following commands to execute the code.

Language	Command
c++	cmake --build . && ./main
haskell	cabal test
j	jconsole main.ijs, then type e.g. ex01
julia	julia, type include("main.jl") and e.g. ex01(ex01_input)
lisp	Send the entire Emacs buffer to SLIME
perl	./main.perl
python	phython main.py
prolog	swipl main.pl, and type ex01(A, B).
rust	cargo check
