Red, never.

Is it possible to view test cases of these problems?

I tried hacking a couple of O(NK^2) solutions but they both failed :(

You can replace the inner dp with fft to get a runtime of O(N*Klog(K)).

So this is what happened today:

• I solved A, B, C, D, E and was finally about to be master *_*
• Plot twist 1: 5 mins after the contest, my D got hacked. No master for me :(
• Plot twist 2: A lot of people had their D hacked. I was going to be a master after all *_*
• Plot twist 3: My C got hacked. Oops, not going to be a master :(

Requesting all hackers to add another plot twist here (By hacking other people's solutions, not mine :P)

I got this right but still got hacked, any other case?

Why is the system test still pending? Are you guys intentionally trying to make it the worst contest ever now?

No, just guys with kawaii girl profile pictures.

During a practice session:

"I'll take a Div 2A and SOLLVE IT!"

P.S: DeathNote reference.

Wrong move.

403 is everywhere, even in this guy's username aryanc403

Delay in System tests?

So the Fastest Solution for COOLCHEF is O(NQlogN)

There's a typo in the title, perhaps you meant SRM 760?

Regarding Amazon gift cards, apparently, they cause some tax claim issues :(

How did he manage to create an account with the exact same username :O

Damn, that was a tough contest. How to solve A,B,C and D?

Not sure if it's a typo or you're just promoting pride month XD

Taiwan and William Lin be like:

Still waiting for the rating update...

Oh that's sad! Will the events be held simultaneously or is it possible to participate in both? If not, it's up to the participant to choose the event?

What happens if someone qualifies for both TCO India regionals and TCC regionals? Do they receive double reimbursements?

I think what he means is the penalty would be different for each user. If you didn't submit an AC solution at all before rejudge, it would not affect you.

Also, can we expect expectation problems?

Will mere mortals survive this?

Isn't that tomorrow?

Soon?

Just to make people curious about nothing XD

I didn't listen to twice and now I have -270 in 2 contests. :(

I can help you become blue if you're purple.

Seems like I'm having symptoms of "Dreadful Days" too.

What's with all these female anime character profile pictures?

For contests like these, you should get my script which sorts problems by number of submissions :)

Same, I tried hacking but cf was too slow at the end :(

It doesn't show Topcoder contests anymore :(

Ashishgup kitne paise diye promotion ke liye? XD

I hope we're alternating between upvotes and downvotes here XD

How did he manage to get 7 fake accounts in same room?

What does "Tried to" mean? Did it pass pretests?

Isn't that O(Q(logn)^3), why were the constraint for Q so high (5*10^5)? or is there some observation to improve the time complexity?

Mixing up loop variables. I do this quite often:

for(i=0;i<n;i++)
{
 // lots of code
 for(i=0;i<x;i++);
}

My respect for you increases with every detail that you add.

How to solve the expectation problem?

=0 ?

I guess they don't verify those cases.

Can't access the contest, is it accessible only to women?

Who is Ram and what makes you think they want him to qualify so badly?

Others come and go but there's one guy who's always at the top \(*^*)/

Luckily overflow results in values modulo 2^31 or 2^63 so it doesn't change the parity.

Also, me using DSU for B.

What's the other cp?

I appreciate the effort, but tbh it doesn't look as good as I would like :(

m-i might become negative.

If you want to automate the process for all teams, you can use my script here:

I got a mail for clearing the online round but my cool down period has not ended yet, so didn't go further with it :(

Would be nice if you could add team rating to the table.

Is this from Codechef's certification exam? In that case the constraint was

0<=Ai,Bi<=10^6

My solution was the same as mentioned by aviroop123 and it gave 100 points.

If you have a csv or doc file, you can use:

https://www.tablesgenerator.com/markdown_tables

If you wish to calculate and add team ratings, yuo can use:

https://github.com/abdullah768/Codeforces-Team-Rating-Calculator

It generates results such as:

Why is green more muscular than LGM?

Lance getting upvotes? is 2019 the end of the world? :O

max 1583 -> max 2003 (+420) I hope I'll be a master this year *_*

Contribution hack: Just mention a really helpful person :)

It's his second regional only.

Here's the script that I used:

You might need to change some code if the table is not in the exact same format as mentioned.

Another issue was that there were lot's of announcements for the problems that were not reflected in the printed statements (Almost every problem had an announcement). Thankfully, they weren't mid contest, but was still annoying.

Do you even have enough members to form a team?

There isn't enough space, and the sorted order (No.) gives a rough approximate anyways.

Wtf! Someone deleted the entire table from the sheet. :(

I've restored it to the previous version now.

I didn't know about it. Added a cut after the last team whose members are known.

Done, some names might look weird, but the table is much better than before.

That's because some usernames / Team names have long words in them. I'll add spaces between 2 make it split over 2 lines in the next update.

Here's a similar list for Pune/Gwalior site. Please update over there as well if you're attending / know the usernames of any team. Thanks!

Great work! can we also have such lists for other sites as well?

FFT in 15 lines? wow. Can you please provide a link to the implementation?

It is funny, but is it worth it?

Has there ever been a rated team contest?

can you update the script for the new c++ versions?

Can someone elaborate why this works and what's the intuition behind it?

"Is it rated?" Life Hack: Read the title!

ceil?

Wait, I was talking about the brute-force factorisation method which does not even need any modulo :/

With competitive programming (1 sec TL) point of view, isn't it worse than the simple O(root(N)) factorisation?

I used to use gmail login, just changed password and it says "Invalid handleOrEmail/email or password" on the back up website :/

Pleasure! :)

This could be used as a problem statement starter XD

This worked perfectly!
