Modifying the content of Git submission is equivalent to rewriting history, and be cautious. For the most recent commit, use git commit --amend to correct it. If you need to modify the earlier commit, use git rebase -i. Note that modifying history may cause collaboration problems, you should use git rebase with caution, and it is best to make backups. Keep the scope of modifications small when submitting, write clear information, and use git log to view history reasonably.
