If you're interested in learning, you might want to first review our FAQ page https://www.hackerrank.com/faq and the tutorials track on our site
https://www.hackerrank.com/domains/tutorials/. We offer a "30 days of Code" subdomain and a "Cracking the coding interview" subdomain ( includes video tutorials).
For additional help you might also want to check the discussion area, which is a forum moderated by HackerRank. You may find that other users may have run into the same issue and received a resolution.
If you are still stuck, you can unlock the editorial solution, which explains how to solve the challenge. You can also go to the leaderboard and reveal other users' solutions.
**Note, if you view the editorial or unlock the other users' solutions, you typically (depending on the challenge) will not be eligible to score more points for that challenge.
