How to ask the AI
In addition to sorting by length, tell the AI that this should be a stable sort, meaning words of the same length must keep the order in which they appeared in the input.
If you ask vaguelyWhen there are multiple words of the same length, the input order may not be preserved, breaking the stability of the sort.
