submissions are getting queued :(
It seems there is a slight delay in judging the received submissions. We sincerely apologize for any inconvenience caused.
long queue
Due to heavy delay in the submission queue, the contest has been extended by 30 minutes.
It says contest is over..what does it mean?
Unfortunately due to some technical issues, the contest has been abruptly ended by Codechef. Sorry for the inconvenience.
Is there any chance the contest will continue if the issues will be resolved quickly?
No actually, we will email all the participants about the update.
That's a complete fuck-up then. Nobody will have a chance to correct the submissions, which finally got judged after the long time in queue.
It was announced that the contest has been extended by 30 Minutes. But the submission has already been turned off even before the 30 minutes of the initial ending time. :)
How to do Pyro Billboard? I tried flipping those bits who are set for even number of elements in the array, but failed.
Can anybody help, please?
You can flip only one bit per each element.
So I have printed $$$min(ans, n)$$$.
Why won't it work?
Because you're not doing what's supposed. Look on test 536870911 536870912 for example. What does your code return here? 2?
How to solve Nachiket and Supernova?
It was an FFT problem. Here is the Author's Solution for the same: https://ideone.com/HIEzzC
We will be releasing video editorials in the next few days.
Most questions from the contest were minor modifications on standard problems.
The DSU problem was exactly CF: Connected Components?
This FFT problem is on CSES.
