Bengalis, assemble.... খেলা হবে । সবাই খেলবো ।

The hacker can hack as many solutions as he/she can during the hacking phase. Once the hacking phase is complete, the system testing phase tests all solutions with all testcases before finalising the ranklist so that no faulty solution gets accepted.

Yes, that particular testcase gets added to the set of testcases. During system testing, all solutions are judged with all testcases (including the ones which successfully hacked a solution).

Good luck CodeChef. I have doubts if this will go well. Even CF servers fail to handle load at certain times. I am not sure if CC really has a position to throw such a challenge.

It's still rated. The CodeChef team is looking into it.

The CodeChef dev team is looking into it.

The time limits have been verified by multiple testers. Try to come up with a more optimised solution.

Sure, they are ready.

Actually, since this contest is rated for both divisions, the problems have been verified and tested by the CodeChef admins. Therefore, you can expect a decent problemset in this contest. We'll be more than glad to hear the feedbacks from you after the contest.

We hope to see you in the ranklist. :)

Nice idea, we will think of renaming it from next year onwards.

An acknowledgement from the testers boosts the confidence of the participants, nothing else ;)

Following the trend, any review from the testers?

O(n) Pypy2 solution TLEs. Link: https://mirror.codeforces.com/contest/1328/submission/74427464

Same solution ACs when submitted in Python2. Can anyone explain why?

For C, I tried a randomized approach. I tried to randomly assign values, not already present in the array, at the vacant positions until a valid solution is found. This approach has a success probability of about 36% (link).

However, I don't know why, but the same code received TLE when I submitted it in Pypy2, because of which I ended up spending more than 1 hour for this problem :(

Phew... I thought the newer version is not supported and so I have to reinstall the outdated one.

The predictor was working fine till yesterday. However, today I updated my Firefox web browser and it's not working anymore. I am running Firefox Quantum (64.0) in Ubuntu 18.04.

Wow!!! Excellent solution.

Yes sir, I've got my answer. Thanks a lot.

Thanks a lot.

I think you are right. But I've never used the 'flush()' method. And that's I thought 'print' prints in real-time.

My solution: https://mirror.codeforces.com/contest/1011/submission/40799411

'print 1' prints '1'. I don't think we can flush this again.

In Problem D, I couldn't accept the input using Python 2.

My simple solution:

n, m = map(int, raw_input().split())
print 1
raw_input()

The verdict: Idleness limit exceeded.

Any help is appreciated.
