Hello everybody!

Vladosiya and his team are good at creating Div. 3 if you look at all Vladosiya's flashings, then there is only a Div. 3.

It's ironic that all the testers are not actually eligible for Div. 3... — by cry

The competition itself is an interesting Div. 3 and $$$3-eights$$$

Also, if you decompose the number $$$8$$$ into multipliers, you get $$$2 ^ 3$$$.

I'm wondering if Codeforces Round 777 (Div. 2) was interesting or not. I didn't participate in this competition so I don't know.

I hope that Vladosiya will live up to expectations, and I wish you good luck!
