Firstly, you should assume we know what you are talking about, rather 
than explain in clear terms. Never show us an example of your data 
structure. That way we can have the entertainment of guessing what the 
structure of the data structure is, and coding for data that you don't 
care about.

Secondly, never tell us what (if anything) you have already tried, so 
that we can share in the same dead-ends and failed attempts. Share and 
share alike.

Thirdly, make sure we don't have a clear idea of what you consider 
"best", e.g. fastest to write, fastest to execute, most readable, most 
easily maintainable, most memory efficient, short enough to be used as a 
one-liner, or something else. For bonus points, this shouldn't be clear 
in your own mind either.

Fourth, never be clear about the functional requirements. For example, do 
you want to mutate the data in place? Or should the original data remain 
untouched, and a modified copy be made? By leaving this unstated or 
subtly implied, you can ensure that our answers have a 50% chance of 
getting it wrong.

If you keep these points in mind, you too can ask open-ended, poor 
questions that generate much discussion but don't solve your actual 
problem.

Oh wait, I see you already know this! Sorry for the noise.
