Imagine this situation: I am working on a university programming project with another classmate. We agree that I do section A, and he does section B. I finish section A early and decide to also do section B for fun. I finish section B. In the meeting with my group mate we realise my section B is much better than his. So we use my section A and my section B for the final project. We decide to also include his section B in the final code to show that he did his part, though his section B is unused by any of the program built from the combined code. What word can I use to refer to his code. There is a word, similar to garbage, that I can't seem to remember.
