How to ask the AI
Tell the AI that the input is a single line separated by half-width spaces, and whether there might be extra spaces between words. Being mindful of how split behaves and checking with concrete examples helps put your mind at ease.
If you ask vaguelyIf the input format is left ambiguous, the AI may write code that assumes line breaks or commas as separators.
