Hello!

Recently, Codeforces hosted 4 rounds in two days — 388, 387, 386, 385 Div 1/Div 2.

Usually pauses between rounds are much large. This time, three of the four rounds were based on the onsite contests in Saratov and Samara, so the date of the rounds were attached to these events.

I've prepared some interesting statistics: 450 people participated in each round and solved at least one problem in each of them. Wow! We did not expect it would be so much less enthusiastic participants. So happy! :)

And here is a list of our heroes (found yourself?):
