C++ Dataset Needed Where There Is A Question Giving With The Responce Code From A Student AND A Teacher.

i need a dataset where there should be a question based on which a students writes a code then a teacher writes a code. I tried to find it on the web but came up with nothing. If both student and theacher’s code in a single file is not possible I would also like a seperate dataset meaning the questions are not the same for both parties. I need this to compare the quality of the code.

Thank you!
