As an optimization, you might want to reuse a buffer like a scratch pad, but even then prefer to Restrict the variable’s scope as much as is possible and be mindful not to cause bugs from info left inside of a recycled buffer as it is a prevalent source of security bugs.

A lot more specialized procedures are sometimes a lot easier to understand and also to implement, but devoid of typical regulations, they might just be a protracted listing of special conditions.
