The docstring is missing a URL reference to Wikipedia or another similar explanation. According to the project's CONTRIBUTING.md, all new algorithms must include at least one URL that points to Wikipedia or another similar explanation. Consider adding a reference such as https://en.wikipedia.org/wiki/Parity_(mathematics) at the beginning of the docstring or as a module-level docstring.

The function is missing doctests, which are required according to the project's CONTRIBUTING.md guidelines. All functions must include doctests that pass automated testing. Please add example test cases in the docstring showing the function's behavior with various inputs (e.g., positive even numbers, positive odd numbers, zero, and negative numbers).
