Ask HN: Simple programming problems that ChatGPT can't solve

Access to ChatGPT is now allowed for anyone. Also, it is very good at solving programming problems at a level that are good exercises for beginners. Students may use it to solve problems like 4th graders use calculators for math problems and skip the joy of the learning process. I wonder what would be a good list of interesting programming problems that are good for developing programming skills and hard for ChatGPT to solve. Anyone knows any?
