This is an ongoing PRACTICE site for the 2018 competition now that it has closed. See https://persecoding.net for competition details and the questions and testcases that we used for the 2018 competition. We hope to be BACK in 2019 so stay tuned and keep practising!
Please note that the leaderboard within the hackerrank competition IS NOT the same as the way that the competition is scored which is team pairing combined total. See our website for more details.
