Hi community,

I'm glad to invite you to my first contest, Codeforces Round 652 (Div. 2) which will be held at Jun/23/2020 17:05 (Moscow time) ($$$\text{notice the unusual time}$$$). The problems are mainly prepared and invented by me. The round is rated for participants with rating strictly less than $$$2100$$$, others are able to take part in the round out of competition. You will be given $$$2$$$ $$$\text{hours}$$$ to solve $$$6$$$ $$$\text{problems}$$$.

Firstly I'd like to thank adedalic for coordinating and reviewing the round, as well as helping with many different things.

I'd like to thank antontrygubO_o, physics0523, McDic, Ashishgup, dannyboy20031204, Kuzey, SinaSahabi, FieryPhoenix, ma_da_fa_ka, ITDOI, AM_I_Learning, awoo, lynmisakura, JustasLe and ArimeZ for testing the round and giving valuable feedback.

Also I'd like to thank coauthors, amiralisalimi, AS.82 and davooddkareshki for helping me with inventing and choosing the problems.

Finally, thanks to MikeMirzayanov for very nice and convenient Codeforces and Polygon platforms.

I wish you all will find the problems interesting, thank you for participating, and good luck!
