I saw this article and fed ChatGPT a bunch of questions I've seen before in my coding interviews. It nailed most of the algorithms, however, it failed completely giving me test cases it would run to test the function it just regurgitated. ie...it gave me an input then mostly incorrect/invalid expected outputs.
