With his second place on Global Round 10, maroonrk has once again become the highest rated user without a single Codeforces Round win!

He has previously held the coveted record for a long time, before briefly losing it to yutaka1999, who hasn't even competed since 2019.

With this near win, maroonrk has now bagged 7 second-places, yet still trails behind DestinyFucker9000 in terms of round wins.

Hello Codeforces!

I am glad to invite you to Codeforces Round #601, which will take place on Nov/19/2019 17:35 (Moscow time). The round will be rated for both divisions.

All problems in this round were created and prepared by a team of all-Vietnamese setters: MofK, I_love_tigersugar, UncleGrandpa, ngkan. This is the first Vietnamese Div1 round. We tried to make both the problems and the statements interesting and hope that you will enjoy them!

There is an interactive problem in the round. You can read the guide for interactive problem here.

We would like to give a lot of thanks to:

We wish you an exciting round!

UPD: The message from MikeMirzayanov. If the issue heavily affected you and you want the round to be UNRATED for you, you can fill the appeal form by the link: https://codeforces.me/userForm/f0458e24fa295 Please do not fill it just in case. Be honest, fill in only if the problem broke your participation in the contest. Mike.

UPD: There will be five problems for Division 1 and six problems for Division 2. The score distribution is as follows:

Division 1: 750 — (500 + 750) — 1500 — 1750 — 2500

Division 2: 500 — 1000 — 1500 — 1750 — (1000 + 1250) — 2750
