The nim compiler we'll use for this project is version 0.17.2.

Everything you need is already installed on CS department lab machines.

To install on your virtual machine, follow these steps:

  1. Run sudo apt install -y nim

How I will run your code

The programs you submit should be in a single file called proj.nim, for either part of the project. I will test your code by running the following commands using the software available in the lab environment or using the instructions above:

nim c proj.nim
