It depends. A static variable means you have one variable that’s shared across all recursive invocations. A normal local variable means each recursive invocation gets its own copy of that variable. You need to choose the one that makes sense for what you’re doing.
A global is like a static local variable (one variable shared by all invocations) but it’s also visible to the rest of the application.
