Hello!

I'm glad to invite you all to Round 485 which will take place on Tuesday, May 29 at 18:35 UTC+3.

There will be 6 problems in each division, 3 of them is shared between divisions. 2 of div.2 problems are by KAN, 7 others are by me. The contest duration is 2 hours. My problems were originally used in HSE Championship.

I would like to thank Merkurev and GlebsHP with whom I discussed the problems, I_love_Tanya_Romanova for testing, KAN for round coordination and Codeforces and Polygon team for these beautiful problems. I would also like to thank HSE for organizing the event.

For those who for some reason like to know score distribution in advance:
div.2: 500 — 1000 — 1000 — 1500 — 2250 — 3000
div.1: 500 — 1000 — 1750 — 2500 — 2750 — 3000
But I didn't properly discussed it with KAN so this is subject to change :)

Good fun, have problems, read all the luck. As usual.
