How would you solve this problem given the training set and the existing training methods?
How would a human (maybe a 5th grader?) solve this?
A human child would just say “I don’t know”.
Indeed. The child applied intelligence.
The LLM has none, so it relies upon regurgitating what it's ingested, and unsurisingly that includes very little programming Q&A with young children. It has no record of not knowing the answer, and so cannot give this correct response.
