To complete this part of the assignment

You'll know you're done with this part of the assignment when you've done all of the following:

• Check your style: Run `cpplint` on your .cpp file, and fix any remaining problems.
• Turn in code that compiles: Confirm that your code compiles in the docker image with no errors or warnings.
• If you make any changes, redo the last two steps!
• Submit all required files: Make sure that all of the required files show in the VS Code interface as being under version control, and that there aren't any modified files in your local working copy that haven't been committed/pushed.
• Don't submit unnecessary files: Make sure the list of files that show in the VS Code interface as being under version control looks reasonable—that no superfluous files (compiled machine code, MacOS .DS_STORE files, etc.) have been accidentally added to the repository.
• Turn in your work: Submit your code on Gradescope by navigating to the submission page for this assignment and uploading files from your GitHub repository.
• Associate all team members with submission: After one person uploads your files on Gradescope, click the Add Group Member button on the right-hand side of the page to make sure all team members are associated with the submission. You will lose points if both team members submit to Gradescope!!
• Check your results: Gradescope will provide feedback on your code. If there are any errors indicated, you are encouraged to fix your code and resubmit. You may submit as many times as you like.
