What is better than setting one AtCoder Grand Contest? Setting two AtCoder Grand Contests, of course!
AtCoder Grand Contest 020 will be held on Sunday (time). The writer is tourist.
This is the first contest of 2018 counted towards AtCoder Race Ranking. If you get into top 30 in this contest, you will get GP30 scores.
The point values will be 300 — 500 — 700 — 1100 (500) — 1400 — 2100.
Let's discuss problems after the contest.
