If your question contains someone else's code…
For moral, practical, and legal reasons, we are only able to review code that you wrote or code that you maintain. Code Review is not the place to ask about someone else's code.
We also expect you to understand how your code works. If you are seeking an explanation of how your code works, then we will treat the question as if someone else wrote it.

- If you are not seeking to improve the code, but rather just to understand how it works, you may be able to ask a question on Stack OverflowStack Overflow. A good question should mention what the observed behaviour is, and why your expectations differ.
