What are the programs that need to be implemented for good language learning?

Question

Programming

Somewhere on the Internet I came across a list of programs that need to be implemented in a specific programming language in order to understand many of the subtleties of the language.
Now I can't find it. Can you provide a link if anyone remembers?
