Let’s define a Binary Contest: a Codeforces contest whose number consists only of 0s and 1s. Sounds cool, right?↵

The Binary Contest Timeline↵
So far, 9 Binary Contests have been held: 1, 10, 11, 100, 101, 110, 111, 1000, 1001↵
↵
And today is the 10th one: 1010!↵
↵
I've participated in two Binary Contests so far: 1000, 1001↵
↵
If I keep up this streak, the maximum contest I might participate in is 1111. Why? Because after that, the next Binary Contest will be 10000—which is about 8889 contests later! ↵
↵
That’s practically a lifetime in Codeforces terms! Now the real question is—can I make it to 1111? Or better yet, can I set a legendary record of attending every Binary Contest from now on? Or maybe... if I don’t, my son or grandson can. :)) The Binary Legacy must live on.↵

↵
**UPD** (22/05/2026): So the Binary Contests are finally here. The next four are: 1100, 1101, 1110, 1111. And realistically, these could be the last Binary Contests I ever get the chance to participate in.↵
↵
**UPD 2** (18/07/2026): Today is the last Binary contest '1111'. The next one will be 10000, and unfortunately, none of us will be able to participate.
