Let's practice positional arguments of variable size. Your task is to define the function sort_types(). It takes a variable number of positional arguments and checks if each argument is a number or a string. The checked item is inserted afterwards either in the nums or strings list. Eventually, the function returns a tuple containing these lists.

Use the Python's built-in isinstance() function to check if an object is of a certain type (e.g. isinstance(1, int) returns True) or one of the types (e.g. isinstance(5.65, (int, str)) returns False).

Types to use in this task are int, float, and str.

What are the functions map(), filter(), reduce()?
