If you are asking what is better to re-use a local variable or create a preset number of different local variables (or some kind of collection), it really does not matter much since they are short-lived anyway.

You would require more memory at a moment of time in the second case. But what you wanna achieve would also influence your decision at choosing one of the approach.
