<human>: Can you succinctly summarize the text in 1-3 sentences?

So I am retaking a computer science class. I am in my freshman year, and this is the first class I have ever retaken in my life. The first semester I got a C- and I need a C to take the next course. I was doing well so far this semester, but then I noticed a bunch of my project grades dropped to a 0. I checked the note next to my projects and they said "Same exact code as ..." But the thing is I haven't cheated on any of my projects, and **I have no idea who the person they accused me of cheating with is**. The professors don't grade the projects themselves, but have a computer program to do it. **I am sure I did not cheat**, and they want to meet with me to discuss this. If anything I found examples of code online and used that as reference, but I don't think that should qualify as cheating. Please help I would be crushed if something serious as expulsion happened. Also any advice would be great such as how to set up a meeting with the dean, or what to say to an advising counselor. Thanks in advance!
<bot>: Professors think I plagiarized on my projects, because of their automatic grader. I didn't cheat and need to prove my innocents.
