You can simply make the function a template. However, you will need to come up with a solution for the lines 23 and 24, as filling array elements with a fixed double value is not generic, though it might even work for strings (with a warning, at least).
Here is how it could look like:

You can change the input type on line 6 for testing purposes as I commented in the code.
