 You can either view my code directly here on Github (you can open + view code files without issues here) or you download the snapshots.

 ### Downloading code snapshots
 
 You can download all the content of a branch via the "Code" button here on Github. You can then either [clone](https://docs.github.com/en/github/creating-cloning-and-archiving-repositories/cloning-a-repository) the repository or simply download the selected branch content as a ZIP file.

+### Running the attached code

+You can use the attached code simply to compare it to yours. But you can also run it.
