$ git branch -M master
$ git remote add origin https://github.com/leetcode.git
$ git push origin master
Copy the code

There are some local changes, but they are not finished yet and need to change other things

#Hide the files modified in the current workspace
$ git stash -m 'create user function - undone'
#View the Hidden list
