it's a good platform and every KING can have another good daybeing an alt on CodeForces.

yes

i am the POET

i am going to show the poem

i have

a new comment

it

says reaching pupll after

the

contest

i am willing to reac h

oupil

without having another good day being a

king.

it is said that people with rating between 0 and 2099 could participate in div 2 contests.

but $$$\color{gold}{\text{K}}\text{ing}$$$ s can also join the contest.

it seems that Mike built a small bug, and pls fix it

i think $$$\color{gold}{\text{K}}\text{ing}$$$ s could only join div 5 contests.

Hello CodeForces community!

I noticed that some greedy problems are used in passed Div.2 as problem A/B have very large limits like $$$n \ge 10^5$$$, is not friendly for coders who don't know sorting skills.

Why? I think we should let all sorting algorithm pass these problems, including the following code:

vector<int> Sort(vector<int> x){
    vector<int> rnk(x.size());
    iota(rnk.begin(),rnk.end(),0);
    do{
        if(is_sorted(rnk.begin(),rnk.end(),[&](int a,int b){return x[a]<x[b];})) break;
    }while(next_permutation(rnk.begin(),rnk.end()));
    vector<int> res;
    for(auto id:rnk) res.push_back(x[id]);
    return res;
}

So I advise that we should let these problems' limits less than $$$8$$$.

Thanks, please upvote this.

I think the gap between the contests may be irregular, now we have 4 contests in 5 days, but last month we even don't have contest during more than 10 days!

I this we should solve this problem, work and rest regularly is important for our health. We shouldn't become less healthy because of CP, right?

If you agree with me, please upvote it.

Hi CodeForces Community!

I think that current rating system is bad. It's not enough friendly for beginners when they found that they are newbies while some users are LGM or even T.

This is not good. The gap may let beginners feel they are hopeless to become good programmers.

To solve the problem, maybe we should let users who registered in 6 months change themselves' rating and rank. Although their extra rating will be removed after 6 months after registration, it may give beginners hope.

Hello, CodeForces Community!

Today I found that some participants in recent Div. 1 Rounds had very good delta. (For example: 251Sec reached GM with +268).

Because I want have higher rating and beat tourist, I need to have the chance to participant the Div. 1 Rounds to get more rating. So I wish that users with the rating below 1900 can choose either Div. 1 or Div. 2, please give me the chance.

Z.

Since Codeforces is the biggest CP platform around the world.

You can post some comments under contest announcements about everyone will lose rating.

Also you can post some useless blogs like this.

The recent contest often have strange time, what's the reason?

The old time of the next contest(9:05 at UTC+9) is good for me, why changed again?

The strange time will make our Asiatics can't do the contest. If you want me to get up at 4:35A.M for a contest? And chinese people to get up at 3:35 A.M for a contest?

14:35(UTC) is fit for most of people in the world(at least it's not too late), why change it often?

Please pardon my poor English.
