4. Push back your work to YOUR remote repository, not to the one that you cloned. Everyone
has their own repository to deliver this assignment, e.g., https://git.cs.dal.ca/courses/2021-
summer/csci-5308/assignment2/yourscid.
5. Remember to check that all your files have been submitted using the web interface to git.
