Hello Codeforces! We (dqa2021, Xiejiadong, Retired_xryjr233, Z18 and me) are excited to invite you to take part in Codeforces Round #664 (Div. 1) and Codeforces Round #664 (Div. 2), which will happen on Aug/12/2020 17:35 (Moscow time).
Huge thanks to:
- 300iq for coordinating our round.
- triple__a for answering my questions about contest preparation.
- duyiblue, jhdonghj112, amiya for providing and discussing ideas.

There will be 5 problems in Div.1 round and 6 problems in Div.2 round. You'll be given 2 hours to solve them.
The story of this round is about that man. Instead of displaying his name, I prefer telling one of his legends (or joke):
"I have a 'friend', who makes lots of money every day, earning a billion in the blink of eyes. With a wave of his hand, OIers all over the world will follow him."
You can post your guesses in the comments.
UPD: Score Distribution:
- Div.1: 500 — 1000 — 1500 — 1750 — 2500
- Div.2: 500 — 750 — 1000 — 1250 — 1750 — 2250
UPD: Congratulations to the winners!
