ACL Beginner Contest Announcement

posted:
Since we have to cancel the ACL Contest, we will hold <a href="https://atcoder.jp/contests/abl">ACL Beginner Contest</a> instead. Like ACL Contest, majority of problems will require AtCoder Library. However, the problems will be significantly easier and they will mainly focus on the typical applications of algorithms in ACL. The rated range and the target audience will be the same as ABC. - Contest URL: https://atcoder.jp/contests/abl - Start Time: http://www.timeanddate.com/worldclock/fixedtime.html?iso=20200926T2100&p1=248 - Duration: 100 minutes - Number of Tasks: 0 - Writer: <a href="/users/rng58_admin" class="username"><span class="user-unrated">rng58_admin</span></a> - Rated range: ~ 1999 The point values will be 100-200-300-400-500-600.
