In a vague attempt to keep my sanity intact, I wrote some (quick and dirty) scripts in this folder to automatically generate the folder structure, based on the details within Folder_Names.csv. It would be nice to scrape the details directly from Project Euler, but it didn't seem worth it for just 100 challenges.
My nasty method involved copy-pasting the titles from the archives section into a .csv file to use as the "title", sanitising the name with underscores etc. to use as the "folder", and generating the link automagically. This is trivial since someone at Project Euler was nice enough use easy-to-generate links like https://projecteuler.net/problem=1.
Then, I wrote a quick PowerShell script to create the folders inside src and initialise a README.md (so the folders can be committed with git).
To add more challenges, simply add more rows with the relevant data into File_Names.csv, and then run Create_Folders.ps1 from within the scripts folder (It relies on relative paths from scripts/... sorry!).
Alternatively, if you're annoyed enough by this approach, feel free to make an automagic tool that can scrape the Project Euler archives to create the folders without manual intervention. I certainly won't complain if you PR this in either...
