Hello, I see this submission 269989396 and 269931958, 270012828 and 269983795.

I was able to find 270012828 and 269983795 because of the smart hacking test case (test 18). 270012828 and 269983795 both get TLE on this test.

269989396 clearly obfuscate the code. He put a lot of stupid comment in his code.

If you remove the comment then 269989396 and 269931958 looks the same.

These submission clearly cheats.

This code memset 3e5 element every testcase.

With 10^4 test case, the number of operation is equal to 3*10^9.

So why does it run in 1.5s. As I know, C++ run 3*10^8 operation every second.

Is it because CF judge is fast?

Note that this is not because the test is weak, test case 3 has 10000 test case. Still, the code can pass this test

Why is vjudge down vjudge1 mnxnly278

So when I check the standing of Codeforces Round 917 (Div. 2) I see some sussy unrated account doing contest and the submit time is very close.

https://codeforces.me/contest/1917/standings/participant/170578689#p170578689

When I check their code, I see that they only add a few stupid template and change variable name to avoid the checker. 238719146 238718882 238719053

I think MikeMirzayanov should ban them and recaculate the rating.

Hello, this blog is just my suggestion, please don't downvote me.

These days, Codeforces round problem have too much observation problem and little algorithms problem.

Please authors, can we have more less observation, less constructive algorithm and more algorithms round :)

P/s: This is just my suggestion, if it is not good, please don't downvote me.

Please update problem rating MikeMirzayanov

My screen get unexpectedly big on Win 10 and every text go soft. I update my driver but it didn't solve the problem. How can I get my screen back to normal?

Update: Solve the problem everyone, we need to shut down the computer and turn it on again after update driver (Restart don't work we need to completely shut it down)

I want a TLE bot for my server but the bot is dead.

How can I add the bot to the server if I can't host the bot?

Funny Meme.

By the way, when I get a -25 contribution, I thought why don't get more downvotes and set a record for most negative contributions. So downvote me.

I am just wondering why there isn't any rated contest on Codeforces in IOI mode.
