• [2018.12] I stopped giving the number of the problem or direct links to the sites (Project Euler, HackerRank). Unfortunately, I am still using the name.
• [2019.01] Most of the new solutions are private, especially if the result is not very interesting.
• [2023.03] "Problems 1 to 100 provide a wealth of helpful introductory teaching material and if you are able to respect our requirements, then we give permission for those problems and their solutions to be discussed elsewhere." (https://projecteuler.net/about)
