Guidelines to contribute

1. Cloning git repo -> https://github.com/Amit88k/DSA.git
2. Check all the branches -> git branch -r  
3. switch to the corresponding week branch -> git switch -c [Week branch] => e.g. git switch -c Week1  
4. Go into the directory - [WeekNumber]   
5. Command to go inside the directory -> cd WeekNumber  
6. Add all the files that you want -> git add file1 file2  [if you want to all the files use * instead of files names]  
7. commit with message-> got commit -m "message"  
8. push to the repo -> git push --set-upstream origin [Week branch] => git push --set-upstream origin Week1  
7. Raise the pull request  

NOTE: *Make sure whatever you do, you do in your own direcotry in respective problem and no other file/directory is deleted or tampered due to your submission.
