To save your work you can create an account by clicking the “Sign Up” button. All you need to do is create a username and password and provide an email address. We do not recommend using your real name as your username, instead try think of something fun and memorable. You can also login using an existing Google or Facebook account (click the Google or Facebook logo on Sign Up page).
Hackerrank provides a web based IDE for developing the code for the challenges, but if you are more comfortable in https://replit.com you can also write and debug your code there and then copy and paste it over to Hackerrank when it’s done.
Enjoy the challenge! We look forward to seeing you on July 31st to go over any questions or ideas you’d like to present.
