Revision en38, by AquaMoon, 2021-07-12 02:59:05

Hello, Codeforces!

I'm glad to invite you to Codeforces Round #732 (Div. 1) and Codeforces Round #732 (Div. 2), which will be held on Jul/11/2021 17:05 (Moscow time). Note the unusual start time of the round.

The round will be rated for both divisions. Each division will have 6 problems and 2.5 hours to solve them. There may or may not be an interactive problem, so I suggest you should read the guide for interactive problems.

All problems were written and prepared by CoupDeGrace, kuangbin, mejiamejia, Heltion, Melacau, Nanako, GOATWU, Cirno_9baka, Suiseiseki, ODT, box, Ynoi, syh0313, wh0816 and me.

This is my first round ever. Great efforts have been put in during the past six months. We are sincerely looking forward to your participation. We hope everyone will enjoy it.

Good luck!

UPD1: Here's the score distribution:

Div 1: 500 — 1000 — 1500 — 2250 — (2000+2000) — 4000

Div 2: 500 — 1000 — 1250 — 1750 — 2250 — 3000

UPD2: Sorry to everyone! This is my first round and I spent lots of time to prepare it. I prepared at least 23 problems, and chose these eight ones for this round. I invited 35 testers to test, and chose problems according to their feedback. However, the difficulty is more than expect.And the pretest is not strong, leading to FST for many people. I blamed myself sadly. So I must say sorry to you, my dear friends. I will improve myself in the future. Wish you good luck and happy everyday. (๑•ᴗ•๑)

UPD3: Tutorial is available.

UPD4: Congratulations to the winners
