Calling out all first timers and those new to competitive programming. RookieRank invites all levels of programmers who have never participated in a rated algorithms competition before to experience the thrill! Rookies will have 48 hours to solve 5 algorithm challenges. We will have two leaderboards. One for all first-time competitive programmers. These are users who are not listed on the Algorithms Leaderboard. We will have a separate leaderboard for all rated users. These are users who have participated in rated algorithms contests before.
