I'm going to nominate my re-titling of this question from its original title of "Gives correct output but slow" to "Guess the chocolate box".
I think the new title reflects what it is the code does and contributed to pushing the question onto the HNQ list despite it only attracting a single answer.
I'd like to think that it demonstrated a better titling strategy for a new user for any future questions, however possibly not since they haven't been seen since.
