Just like the Codeforces repository, I will try to organize my code in a way that it'll be easy to search and review.
No pain, no gain.
Work harder, or you will become the loser in this field.
If you only add new folders but no new files such as Readme.md, git add
and git commit won't work. It will throw error messages:
error: src refspec master does not match any.
error: failed to push some refs to 'ssh://xxxxx.com/project.git'"
You can check using git status and git branch,
you will see no branch at all!
