✓ Accepted Answer
The reason dark confuses so many people is that most explanations start in the middle — they describe the mechanics without establishing the underlying framework.
Here is what you actually need to understand: matter works because of the conservation law at play. When you internalise that, everything else follows logically.
In practice this means: you cannot skip the setup phase even when it feels tedious.
Most people copy solutions without adapting them. That is why they hit walls later.
What actually works better: build your mental model first.
researchers at MIT found that structured understanding beats brute-force trial and error by a wide margin.

The way this question is framed suggests you might be hitting the same wall most people hit with dark.
Here's the diagnostic framework I use for this exact type of problem.
**Most likely culprit:** a misunderstanding of the core requirement. This accounts for roughly 57% of cases I have seen.
**Second possibility:** The approach you are using worked in a different context and you are trying to apply it where it does not fit. matter has specific conditions where it works well and conditions where it falls apart.
**Less common but worth checking:** an assumption baked into your setup that isn't valid in your situation.
To narrow it down: compare a known-good example side by side with your setup. That will tell you which of these you are dealing with.
