See [**Problem-Algorithm-Solver pattern**](https://discourse.julialang.org/t/function-depending-on-the-global-variable-inside-module/64322/10). You’ll find the answer there.

No matter how many parameters describe the problem, putting them in _one_ variable makes it easier to pass them as arguments to the function _everytime_.
