Leetcode posts the answers. That could be accomplished by just scraping them. [1] Turing test would be give some vague, underspecified requirements for a system that does not yet exist, and implement a version the requirements writer will accept. Compilers and compiler generators have long been able to generate great code from well-written specifications and no one thinks of them as passing a Turing test. [1] Of course, to some extent, that is what a GPT model is doing anyway. It's able to generate reasonable passing code given just a function prototype because it has scraped and looked at billions of examples of implemented functions with similar prototypes.
